- -Release Date: {{ include.release_date | date: "%B %-d, %Y" }} - -With the release of CockroachDB v19.1, we’ve made a variety of security, performance, and usability improvements. A few highlights: - -- **Enhanced security**: CockroachDB now supports [transparent data encryption at rest](https://www.cockroachlabs.com/docs/v19.1/encryption#encryption-at-rest-enterprise) and [integrates with existing LDAP directory services](https://www.cockroachlabs.com/docs/v19.1/gssapi_authentication) within an organization to simplify user account management. - -- **Native Change Data Capture**: CockroachDB extends its streaming data capabilities by enabling data to flow more easily to backend warehouses, with support for [publishing distributed, row-level change feeds directly into cloud storage](https://www.cockroachlabs.com/docs/v19.1/change-data-capture) for downstream processing. - -- **High-performance multi-region deployments**: Our cost-based optimizer can now [use data locality to optimize queries](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer#preferring-the-nearest-index) so you can get low-latency queries even when your data may be spread across regions. We’ve also added [follower reads](https://www.cockroachlabs.com/docs/v19.1/follower-reads) to improve read performance for certain geo-distributed workloads. - -Check out a comprehensive [summary of the most significant user-facing changes](#v19-1-0-summary) and then [upgrade to CockroachDB v19.1](https://www.cockroachlabs.com/docs/v19.1/upgrade-cockroach-version).

- -This section summarizes the most significant user-facing changes in v19.1.0. For a complete list of features and changes, including bug fixes and performance improvements, see the [release notes]({% link releases/index.md %}#testing-releases) for previous testing releases. - -- [Managed service offering](#v19-1-0-managed-service-offering) -- [Enterprise features](#v19-1-0-enterprise-features) -- [Core features](#v19-1-0-core-features) -- [Backward-incompatible changes](#v19-1-0-backward-incompatible-changes) -- [Known limitations](#v19-1-0-known-limitations) -- [Documentation](#v19-1-0-documentation) - - - -Managed service offering
- -Feature | Description ---------|------------ -[**Managed CockroachDB Console**](https://www.cockroachlabs.com/docs/cockroachcloud/quickstart) | Paid managed CockroachDB customers can now sign into their organization's account, view the connection string details, add and edit their list of allowed IPs on the management console. - -Enterprise features
- -These features require an [enterprise license](https://www.cockroachlabs.com/docs/v19.1/enterprise-licensing). Register for a 30-day trial license [here](https://www.cockroachlabs.com/get-cockroachdb/enterprise/). - -Feature | Description ---------|------------ -[**Encryption at Rest**](https://www.cockroachlabs.com/docs/v19.1/encryption#encryption-at-rest-enterprise) | Encryption at rest provides transparent encryption of a node's data on the local disk. This feature was introduced as experimental in v2.1 and is now ready for production use. -[**GSSAPI with Kerberos Authentication**](https://www.cockroachlabs.com/docs/v19.1/gssapi_authentication) | CockroachDB now supports the Generic Security Services API (GSSAPI) with Kerberos authentication, which lets you use an external enterprise directory system that supports Kerberos, such as Active Directory. -[**Follower Reads**](https://www.cockroachlabs.com/docs/v19.1/follower-reads) | This feature reduces read latencies by allowing queries to perform historical reads of the closest replica of a given piece of data rather than reading from the more distant "leaseholder" replica. To enable follower reads on a query, use the `experimental_follower_read_timestamp()` [built-in function](https://www.cockroachlabs.com/docs/v19.1/functions-and-operators) in conjunction with the `AS OF SYSTEM TIME` clause. -[**Prefer Closest Secondary Index**](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer#preferring-the-nearest-index) | Given multiple identical [indexes](https://www.cockroachlabs.com/docs/v19.1/indexes) that have different locality constraints using [replication zones](https://www.cockroachlabs.com/docs/v19.1/configure-replication-zones), the cost-based optimizer will now prefer the index that is closest to the gateway node that is planning the query. In a properly configured geo-distributed cluster, this can lead to performance improvements due to improved data locality and reduced network traffic. This feature enables scenarios where reference data such as a table of postal codes can be replicated to different regions, and queries will use the copy in the same region. -[**Change Data Capture**](https://www.cockroachlabs.com/docs/v19.1/change-data-capture) | CDC in v19.1 includes many improvements to production-readiness. [`CHANGEFEED`s](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) delivering data to Apache Kafka/Confluent Platform are now fully supported, and a new cloud storage sink allows `CHANGEFEED`s to deliver table updates as JSON files to endpoints like Google Storage or AWS S3. A new push-based internal data delivery mechanism called _rangefeeds_ helps deliver data with increased reliability and lower latency. - -Core features
- -These features are freely available in the core version and do not require an enterprise license. - -Feature | Description ---------|------------ -[**Load-Based Splitting**](https://www.cockroachlabs.com/docs/v19.1/load-based-splitting) | CockroachDB now automatically splits frequently accessed keys into smaller ranges to optimize your cluster’s performance. -[**Query Optimizer Hints**](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer#join-hints) | The cost-based optimizer now supports hint syntax to force the use of merge, hash, or lookup joins. This let you override the cost-based optimizer's join algorithm selection in cases where you have information about your data that the cost-based optimizer does not yet have. -[**Correlated Subqueries**](https://www.cockroachlabs.com/docs/v19.1/subqueries#correlated-subqueries) | Most correlated subqueries are now decorrelated and processed by the cost-based-optimizer. For those that cannot be decorrelated, CockroachDB now emits an "apply" operator that executes a sub-plan for every row in its input. This allows CockroachDB to execute a large number of additional correlated subqueries that were not able to be executed in v2.1. -[**Core Changefeeds**](https://www.cockroachlabs.com/docs/v19.1/changefeed-for) | CockroachDB now offers a non-enterprise version of change data capture, via the `EXPERIMENTAL CHANGEFEED FOR` statement, to consume table updates over a streaming Postgres connection. -[**Cost-Based Optimizer**](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer) | The cost-based optimizer now supports almost all read-only queries (except window functions) and almost all mutations (e.g., `CREATE TABLE AS`, `INSERT`, `UPDATE`, `UPSERT`, `DELETE`). In addition, the cost-based optimizer now reorders up to 4 joins in a query to attempt to find the most performant ordering (via the new `reorder_joins_limit` [session variable](https://www.cockroachlabs.com/docs/v19.1/set-vars)) and takes advantage of [automatically generated table statistics](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer#table-statistics) without impacting foreground traffic. Note that statistics are created by default on all indexed columns when a user upgrades to this version. Finally, a [query plan cache](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer#query-plan-cache) now saves a portion of the planning time for frequent queries used in the cost-based optimizer. -[**Logical Plans in the Admin UI**](https://www.cockroachlabs.com/docs/v19.1/admin-ui-statements-page#logical-plan) | The **Statement Details** page in the Admin UI now shows the ordered steps CockroachDB will take to execute a query (i.e., the [`EXPLAIN`](https://www.cockroachlabs.com/docs/v19.1/explain) output). This helps you identify bottlenecks caused by how queries are planned by our heuristic and cost-based optimizers. -[**Cascading Replication Zones**](https://www.cockroachlabs.com/docs/v19.1/configure-replication-zones) | Newly created replication zones will now inherit empty values from their parent. For example, if the replication zone for a table is not explicitly set with `num_replicas`, it will inherit that value from its direct parent, whether that's the `.default` replication zone from the entire cluster or the replication zone for the database containing the table. -[**Custom Savepoints**](https://www.cockroachlabs.com/docs/v19.1/savepoint#customizing-the-savepoint-name) | CockroachDB now supports custom naming of `SAVEPOINT`s for compatibility with ORMs and other third-party tools. - -Backward-incompatible changes
- -Before [upgrading to CockroachDB v19.1.0](https://www.cockroachlabs.com/docs/v19.1/upgrade-cockroach-version), be sure to review the following backward-incompatible changes and adjust your application as necessary. - -- CockroachDB no longer supports the `B'abcde'` notation to express [byte array literals](https://www.cockroachlabs.com/docs/v19.1/sql-constants#byte-array-literals). This notation now expresses **bit** array literals like in PostgreSQL. The `b'...'` notation remains for byte array literals. - -- The normalized results of certain timestamp + duration operations involving year or month durations have been adjusted to agree with the values returned by PostgreSQL. - -- The `CHANGEFEED` [`experimental-avro` option](https://www.cockroachlabs.com/docs/v19.1/create-changefeed#options) has been renamed `experimental_avro`. - -- Timezone abbreviations, such as `EST`, are no longer allowed when parsing or converting to a date/time type. Previously, an abbreviation would be accepted if it were an alias for the session's timezone. - -- The way composite [foreign key](https://www.cockroachlabs.com/docs/v19.1/foreign-key) matches are evaluated has changed to match the Postgres behavior. If your schema currently uses composite keys, it may require updates, since this change may affect your foreign key constraints and cascading behavior. For more details and guidance, see [this note](#v2-2-0-alpha-20190114-composite-foreign-key-matching). - -- Mutation statements like [`UPDATE`](https://www.cockroachlabs.com/docs/v19.1/update), [`INSERT`](https://www.cockroachlabs.com/docs/v19.1/insert), and [`DELETE`](https://www.cockroachlabs.com/docs/v19.1/delete) no longer attempt to guarantee mutation or output ordering when an `ORDER BY` clause is present. It is now an error to use `ORDER BY` without `LIMIT` with the `UPDATE` statement. - -Known limitations
- -For information about limitations we've identified in CockroachDB v19.1, with suggested workarounds where applicable, see [Known Limitations](https://www.cockroachlabs.com/docs/v19.1/known-limitations). - -Documentation
- -Topic | Description -------|------------ -**Geo-Partitioning** | Added a [video and tutorial on using geo-partitioning](https://www.cockroachlabs.com/docs/v19.1/demo-geo-partitioning) to get very fast reads and writes in a broadly distributed cluster. -**Security** | Added an [overview of CockroachDB security](https://www.cockroachlabs.com/docs/v19.1/security-overview), with a dedicated page on [authentication](https://www.cockroachlabs.com/docs/v19.1/authentication), [encryption](https://www.cockroachlabs.com/docs/v19.1/encryption), [authorization](https://www.cockroachlabs.com/docs/v19.1/authorization), and [SQL audit logging](https://www.cockroachlabs.com/docs/v19.1/sql-audit-logging). -**Troubleshooting** | Added much more guidance on [troubleshooting cluster setup](https://www.cockroachlabs.com/docs/v19.1/cluster-setup-troubleshooting) and [troubleshooting SQL behavior](https://www.cockroachlabs.com/docs/v19.1/query-behavior-troubleshooting). -**Architecture** | Added the [Life of a Distributed Transaction](https://www.cockroachlabs.com/docs/v19.1/architecture/life-of-a-distributed-transaction), which details the path that a query takes through CockroachDB's architecture, starting with a SQL client and progressing all the way to RocksDB (and then back out again). Also added [Reads and Writes in CockroachDB](https://www.cockroachlabs.com/docs/v19.1/architecture/reads-and-writes-overview), which explains how reads and writes are affected by the replicated and distributed nature of data in CockroachDB. -**Production Guidance** | Expanded the [Production Checklist](https://www.cockroachlabs.com/docs/v19.1/recommended-production-settings) with more current hardware recommendations and additional guidance on storage, file systems, and clock synchronization. Also added a library of common [Cluster Topology Patterns](https://www.cockroachlabs.com/docs/v19.1/topology-patterns). -**ORMs** | Expanded the [SQLAlchemy tutorial](https://www.cockroachlabs.com/docs/v19.1/build-a-python-app-with-cockroachdb-sqlalchemy) to provide code for transaction retries and best practices for using SQLAlchemy with CockroachDB. diff --git a/src/current/_includes/releases/v19.1/v19.1.1.md b/src/current/_includes/releases/v19.1/v19.1.1.md deleted file mode 100644 index 01beef8072f..00000000000 --- a/src/current/_includes/releases/v19.1/v19.1.1.md +++ /dev/null @@ -1,67 +0,0 @@ -{{ include.release }}

-- The experimental cloud storage changefeed sink previously violated some of the changefeed invariants under rare conditions. A number of these have been fixed, but some fixes require changes to the format of the filenames output by the cloud storage changefeed. This is unsuitable for inclusion in a patch release, so users of cloud storage changefeed sinks are highly encouraged to upgrade to CockroachDB 19.2 or later.

[#41699][#41699] -- Fixed a bug causing rapid network disconnections to lead to cluster unavailability because goroutines waited for a connection which will never be initialized to send its first heartbeat. [#42165][#42165] -- Fixed an internal error in a rare case involving `UNION` and tuples inside `VALUES` clauses. [#42266][#42266] -- CockroachDB now permits planning of window functions within mutation statements, and other statements that cannot be distributed.

[#42764][#42764] -- [`ALTER INDEX IF EXISTS`](https://www.cockroachlabs.com/docs/v19.1/alter-index) no longer fails when using an unqualified index name that does not match any existing index. Now it is a no-op. [#42839][#42839] -- CockroachDB now prevents a number of panics from the SQL layer caused by an invalid range split.

[#43027][#43027] -- Fixed a bug in cloud storage sink file naming that violates ordering in presence of a schema changes. [#43027][#43027] -- Fixed a bug causing disk stalls to allow a node to continue heartbeating its liveness record and prevent other nodes from taking over its leases, despite being completely unresponsive. [#41765][#41765] -- CockroachDB now properly removes excess secondary log files (SQL audit logging, statement execution logging, and RocksDB events).

[#44599][#44599] -- Fixed a bug where running a query with the [`LIKE`](https://www.cockroachlabs.com/docs/v19.1/functions-and-operators) operator using the custom `ESCAPE` symbol when the pattern contained Unicode characters could result in an internal error in CockroachDB. [#44649][#44649] -- Fixed possibly incorrect query results in various cornercases, especially when [`SELECT DISTINCT`](https://www.cockroachlabs.com/docs/v19.1/select-clause#eliminate-duplicate-rows) is used. [#44606][#44606] -- Fixed an internal error that could happen in the planner when table statistics were collected manually using [`CREATE STATISTICS`](https://www.cockroachlabs.com/docs/v19.1/create-statistics) for different columns at different times. [#44443][#44443] -- CockroachDB no longer repeatedly looks for non-existing jobs, which may cause high memory usage, when cleaning up schema changes. [#44824][#44824] - -

- -- Previously, the phase of server shutdown responsible for range lease transfers to other nodes would give up after 10,000 attempts of transferring replica leases away, regardless of the value of `server.shutdown.lease_transfer_wait`. The limit of 10,000 attempts has been removed, so that now only the maximum duration `server.shutdown.lease_transfer_wait` applies. [#47698][#47698] -- The textual error and warning messages displayed by [`cockroach quit`](https://www.cockroachlabs.com/docs/v19.1/stop-a-node) under various circumstances have been updated. Meanwhile, the message "`ok`" remains as indicator that the operation has likely succeeded. [#47698][#47698] -- [`cockroach quit`](https://www.cockroachlabs.com/docs/v19.1/stop-a-node) now prints out progress details on its standard error stream, even when `--logtostderr` is not specified. Previously, nothing was printed on standard error. Scripts that wish to ignore this output can redirect the `stderr` stream. [#47698][#47698] - -Security updates
- -- Non-licensed users are now able to [add more principals](https://www.cockroachlabs.com/docs/v19.1/grant-roles) to the special superuser role/group `admin`. Note: [Creation of additional roles](https://www.cockroachlabs.com/docs/v19.1/create-role) is still a licensed feature. [#45396][#45396] - -General changes
- -- Previously, the phase of server shutdown responsible for range lease transfers to other nodes had a hard timeout of 5 seconds. This patch makes this timeout configurable via the new cluster setting `server.shutdown.lease_transfer_wait`. [#47698][#47698] - -SQL language changes
- -- It is now possible to use [`GRANT`](https://www.cockroachlabs.com/docs/v19.1/grant) and [`REVOKE`](https://www.cockroachlabs.com/docs/v19.1/revoke) to add users to the `admin` role without a valid license. This change aims to enable use of the Admin UI and other privileged features without a license. [#45396][#45396] -- The type checking code now prefers aggregate overloads with string inputs if there are multiple possible candidates due to arguments of unknown type. [#46902][#46902] -- Added a new "unimplemented" error when attempting to [`ADD CONSTRAINT `](https://www.cockroachlabs.com/docs/v19.1/add-constraint) with the `EXCLUDE USING` syntax. [#46912][#46912] -- Added support for using [`CREATE INDEX ... INCLUDE (col1, col2, ...)`](https://www.cockroachlabs.com/docs/v19.1/create-index), which is an alias that PostgreSQL uses that is analogous to our `STORING (col1, col2, ...)` syntax. [#46912][#46912] -- Added support for parsing the `REINDEX` syntax, which results in an "unimplemented" error that explains that `REINDEX`ing is not required in CockroachDB. [#46912][#46912] -- CockroachDB now parses the `CREATE INDEX CONCURRENTLY` and `DROP INDEX CONCURRENTLY` syntaxes, which return errors when used. [#46808][#46808] - -Command-line changes
- -- [`cockroach debug zip`](https://www.cockroachlabs.com/docs/v19.1/debug-zip) now avoids creating invalid zip files if some of its requests encounter an error. [#46637][#46637] -- The time that [`cockroach quit`](https://www.cockroachlabs.com/docs/v19.1/stop-a-node) waits client-side for the node to drain (remove existing clients and push range leases away) is now configurable via the command-line flag `--drain-wait`. Note that separate server-side timeouts also apply separately; check the `server.shutdown.*` [cluster settings](https://www.cockroachlabs.com/docs/v19.1/cluster-settings) for details. [#47698][#47698] -- It is now possible to drain a node without shutting down the process, using [`cockroach node drain`](https://www.cockroachlabs.com/docs/v19.1/view-node-details). This makes it easier to integrate with service managers and orchestration: it now becomes safe to issue `cockroach node drain` and then separately stop the service via a process manager or orchestrator. Without this new mode, there is a risk to misconfigure the service manager to auto-restart the node after it shuts down via `quit`, in a way that's surprising or unwanted. The new command `node drain` also recognizes the new `--drain-wait` flag. [#47698][#47698] -- The default value of the parameter `--drain-wait` for [`cockroach quit`](https://www.cockroachlabs.com/docs/v19.1/stop-a-node) has been increased from 1 minute to 10 minutes, to give more time for nodes with thousands of ranges to migrate their leases away. [#47698][#47698] -- The commands [`cockroach quit`](https://www.cockroachlabs.com/docs/v19.1/stop-a-node) and [`cockroach node drain`](https://www.cockroachlabs.com/docs/v19.1/view-node-details) now report a "work remaining" metric on their standard error stream. The value reduces until it reaches `0`, to indicate that the graceful shutdown has completed server-side. An operator can now rely on `cockroach node drain` to obtain confidence of a graceful shutdown prior to terminating the server process. [#47698][#47698] - -Admin UI changes
- -- Metrics relating to [SQL transaction](https://www.cockroachlabs.com/docs/v19.1/admin-ui-sql-dashboard) restarts and rollbacks are now properly captured and exported. [#46273][#46273] - -Bug fixes
- -- Fixed a "cannot map variable" error in some rare cases involving [joins](https://www.cockroachlabs.com/docs/v19.1/joins). [#44860][#44860] -- Fixed incorrect de-duplication of impure expressions (like `gen_random_uuid`) in projections and default values. [#44916][#44916] -- Fixed an internal error that could occur when `NULLIF` was called with one null argument. [#45391][#45391] -- It is now possible to create [inverted indexes](https://www.cockroachlabs.com/docs/v19.1/inverted-indexes) on columns whose names are mixed-case. [#45678][#45678] -- Previously, drivers that did not truncate trailing zeroes for decimals in the binary format ended up having inaccuracies of up to 10^4 during the decode step. Fixed this error by truncating the trailing zeroes as appropriate. This fixes known incorrect decoding cases with Postgrex in Elixir. [#45671][#45671] -- Fixed a name resolution error that could occur when a [common table expression](https://www.cockroachlabs.com/docs/v19.1/common-table-expressions) (CTE) was referenced in the [`SELECT`](https://www.cockroachlabs.com/docs/v19.1/selection-queries) list of a query using the syntax `Contributors

- -- Load-based splitting is now enabled by default. In conjunction, the `range_min_bytes` setting in the `.default` replication zone is set to a higher value to prevent ranges from unnecessarily being considered for merging. [#31413][#31413] {% comment %}doc{% endcomment %} -- Added a [Kubernetes configuration](https://github.com/cockroachdb/cockroach/tree/master/cloud/kubernetes/bring-your-own-certs) that shows how to use certificates generated outside of the Kubernetes-orchestrated CockroachDB cluster.

- -- The [`EXPERIMENTAL_RELOCATE`](https://www.cockroachlabs.com/docs/v19.1/experimental-features) statement no longer temporarily increases the number of replicas in a range more than one above the range's replication factor, preventing rare edge cases of unavailability. [#29684][#29684] {% comment %}doc{% endcomment %} -- The output of [`SHOW JOBS`](https://www.cockroachlabs.com/docs/v19.1/show-jobs) now reports ongoing jobs first in start time order, then completed jobs in finished time order. The `running_status` column becomes `NULL` when the status cannot be determined. [#30917][#30917] {% comment %}doc{% endcomment %} -- The output of [`SHOW ZONE CONFIGURATIONS`](https://www.cockroachlabs.com/docs/v19.1/show-zone-configurations) now only shows the zone name and the SQL representation of the config. [#30985][#30985] {% comment %}doc{% endcomment %} -- The range log and system events logs now automatically purge records older than 30 and 90 days, respectively. This can be adjusted via the `server.rangelog.ttl` and `server.eventlog.ttl` [cluster settings](https://www.cockroachlabs.com/docs/v19.1/cluster-settings). [#30913][#30913] {% comment %}doc{% endcomment %} -- In cases such as `'2018-01-31'::TIMESTAMP + '1 month'`, where an intermediate result of February 31st needs to be normalized, previous versions of CockroachDB would advance to March 3. Instead, CockroachDB now "rounds down" to February 28th to agree with the values returned by PostgreSQL. This change also affects the results of the `generate_sequence()` function when used with timestamps. [#31146][#31146] -- Updated the output of [`SHOW ZONE CONFIGURATIONS`](https://www.cockroachlabs.com/docs/v19.1/show-zone-configurations).

[#31733][#31733] -- [`CHANGEFEED`s](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) now escape Kafka topic names, when necessary. [#31596][#31596] -- Fixed a bug that would incorrectly cause JSON field access equality comparisons to be true when they should be false. [#31751][#31751] -- Fixed a bug that sometimes caused invalid results or an "incorrectly ordered stream" error with streaming aggregations. [#31825][#31825] -- Fixed a mismatch between lookup join planning and execution, which could cause queries to fail with the error "X lookup columns specified, expecting at most Y". [#31792][#31792] -- Prevented a performance degradation related to overly aggressive Raft log truncations that could occur during [`RESTORE`](https://www.cockroachlabs.com/docs/v19.1/restore) or [`IMPORT`](https://www.cockroachlabs.com/docs/v19.1/import) operations. [#31914][#31914] -- [`EXPLAIN ANALYZE`](https://www.cockroachlabs.com/docs/v19.1/explain-analyze) plans no longer show the processor with ID 0's stats in the Response box. [#31941][#31941] -- Fixed rare deadlocks during [`IMPORT`](https://www.cockroachlabs.com/docs/v19.1/import), [`RESTORE`](https://www.cockroachlabs.com/docs/v19.1/restore), or [`BACKUP`](https://www.cockroachlabs.com/docs/v19.1/backup). [#31963][#31963] -- Fixed a panic caused by incorrectly encoded Azure credentials. [#31984][#31984] -- The [cost-based optimizer](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer) no longer chooses the wrong index for a scan because of incorrect selectivity estimation.

Previously, bound temporal values were always interpreted as though the session time zone were UTC. [#31758][#31758] -- Prevented a stall in the processing of Raft snapshots when many snapshots are requested at the same time. [#32053][#32053] -- [`CHANGEFEED`s](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) now spend dramatically less time flushing Kafka writes. [#32060][#32060] -- Fixed a bug that caused some queries with `DISTINCT ON` and `ORDER BY` with descending columns to return an error incorrectly. [#31976][#31976] -- Fixed a bug that caused queries with `GROUP BY` or `DISTINCT ON` to return incorrect results or an "incorrectly ordered stream" error. Also improved performance of some aggregations by utilizing streaming aggregation in more cases. [#31976][#31976] -- Fixed bit array wire encoding in binary format. [#32091][#32091] -- Fixed a bug that caused transactions to appear partially committed. CockroachDB was sometimes claiming to have failed to commit a transaction when some (or all) of its writes were actually persisted. [#32166][#32166] -- Prevented long stalls that can occur in contended transactions. [#32211][#32211] -- The graphite metrics sender now collects and sends only the latest data point instead of all data points since startup. [#31829][#31829] - -Performance improvements
- -- Improved the performance of [`AS OF SYSTEM TIME`](https://www.cockroachlabs.com/docs/stable/as-of-system-time) queries by letting them use the table descriptor cache. [#31716][#31716] -- Within a transaction, when performing a schema change after the table descriptor has been modified, accessing the descriptor should be faster.

[#32455][#32455] {% comment %}doc{% endcomment %} - -SQL language changes
- -- Users can customize the auto-retry savepoint name used by the `SAVEPOINT` command by setting the `force_savepoint_restart` session variable. For example, `SET force_savepoint_restart=true; BEGIN; SAVEPOINT foo` will now function as desired. This session variable may also be supplied as part of a connection string to support existing code that assumes that arbitrary savepoint names may be used. [#31971][#31971] {% comment %}doc{% endcomment %} -- The names supplied to a `SAVEPOINT` command are now properly treated as SQL identifiers. For example, `SAVEPOINT foo` and `SAVEPOINT FOO` are now equivalent statements. [#31971][#31971] {% comment %}doc{% endcomment %} -- It is now an error to run `ALTER TABLE ... DROP STORED` on a column which is not actually a computed, stored column. Previously, this statement would be a successful no-op. [#32279][#32279] -- Many queries containing a correlated `EXISTS` subquery with a generator function can now be decorrelated and executed successfully. Previously, these queries caused a decorrelation error.

[#32481][#32481] -- An `ALTER TABLE` statement to add a foreign key constraint now automatically creates the necessary index if the referencing table is empty and the index does not already exist. [#32234][#32234] {% comment %}doc{% endcomment %} -- Queries involving `COLLATE` expressions are now supported by the cost-based optimizer. [#32500][#32500] {% comment %}doc{% endcomment %} -- Some categories of `SELECT` queries that return 0 or 1 rows (namely, queries by a PK, a unique index, or LIMIT 1 queries) are now guaranteed to not return retryable errors when running as implicit transactions (i.e., outside of a `BEGIN...COMMIT` block). [#32401][#32401] {% comment %}doc{% endcomment %} -- Added support for `AS OF SYSTEM TIME` with the `CREATE STATISTICS` statement. [#32643][#32643] {% comment %}doc{% endcomment %} -- CockroachDB now accepts ordinary string values for placeholders of type `BPCHAR`, for compatibility with PostgreSQL clients that use them. [#32654][#32654] -- CockroachDB now supports associating comments to SQL tables using PostgreSQL's `COMMENT ON TABLE` syntax. This also provides proper support for pg's `pg_catalog.pg_description` and built-in function `obj_description()`. [#32442][#32442] {% comment %}doc{% endcomment %} -- The `SHOW TABLES` statement now supports printing out table comments using the optional phrase `WITH COMMENT`, e.g `SHOW TABLES FROM mydb WITH COMMENT`.

[#32831][#32831] {% comment %}doc{% endcomment %} -- Added an `experimental_optimize_updates` flag, which uses the cost-based optimizer to plan `UPDATE` statements when set to true. [#32774][#32774] {% comment %}doc{% endcomment %} - -Command-line changes
- -- `cockroach sql` and other commands that print query results and query execution latency will now exclude the time required to prepare the display client-side from the latency measurement.

- -- [Composite foreign key matching](#v2-2-0-alpha-20190114-composite-foreign-key-matching) -- [Mutation statements](#mutation-statements) - -Composite foreign key matching
- -We are changing the way composite [foreign key](https://www.cockroachlabs.com/docs/v19.1/foreign-key) matches are evaluated to match the default Postgres behavior. If your schema currently uses composite keys, it may require updates, since this change may affect your foreign key constraints and cascading behavior. - -Prior to this change, we were matching composite keys with an incorrect implementation of the `MATCH FULL` method, and we are resolving this by moving all existing composite foreign key matches to a correct implementation of the `MATCH SIMPLE` method. Note that prior to this, there was no option for `MATCH FULL` or `MATCH SIMPLE` and all foreign key matching used the incorrect implementation of `MATCH FULL`. - -For a more detailed explanation of the changes, see below. - -For matching purposes, composite foreign keys can be in one of 3 states: - -- _Valid_: Keys that can be used for matching foreign key relationships. -- _Invalid_: Keys that will not be used for matching. -- _Unacceptable_: Keys that cannot be inserted at all. - -The `MATCH FULL` implementation we were using prior to this change allowed composite keys with a combination of `NULL` and non-null values. This meant that we matched on `NULL`s if a `NULL` existed in the referencing column, essentially treating `NULL`s as a valid value. This was incorrect, since `MATCH FULL` requires that if any column of a composite key is `NULL`, then all columns of the key must be `NULL`. In other words, either all must be `NULL`, or none may be. - -To resolve this issue, all matches going forward will use the `MATCH SIMPLE` method (this matches the Postgres default). `MATCH SIMPLE` stipulates that: - -- Valid composite keys may contain no `NULL` values, and will be used for matching. -- Invalid keys are keys with one or more `NULL` values, and will not be used for matching, including cascading operations. - -For more information, see [#32693][#32693]. - -#Mutation statements
- -Mutation statements like [`UPDATE`](https://www.cockroachlabs.com/docs/v19.1/update) and [`INSERT`](https://www.cockroachlabs.com/docs/v19.1/insert) no longer attempt to guarantee mutation or output ordering when an `ORDER BY` clause is present. It is now an error to use `ORDER BY` without `LIMIT` with the `UPDATE` statement. [#33087][#33087] {% comment %}doc{% endcomment %} - -SQL language changes
- -- Added support for configuring authentication via an `hba.conf` [cluster setting](https://www.cockroachlabs.com/docs/v19.1/cluster-settings). [#32892][#32892] {% comment %}doc{% endcomment %} -- Added support for collecting table statistics on a default set of columns by calling `CREATE STATISTICS` with no columns specified. [#32981][#32981] {% comment %}doc{% endcomment %} -- Added the `default_int_size` [session variable](https://www.cockroachlabs.com/docs/v19.1/set-vars) and `sql.defaults.default_int_size` [cluster setting](https://www.cockroachlabs.com/docs/v19.1/cluster-settings) to control how the `INT` and `SERIAL` types are interpreted. The default value, `8`, causes these types to be interpreted as aliases for `INT8` and `SERIAL8`, which have been the historical defaults for CockroachDB. PostgreSQL clients that expect `INT` and `SERIAL` to be 32-bit values can set `default_int_size` to `4`, which will cause `INT` and `SERIAL` to be aliases for `INT4` and `SERIAL4`. Please note that due to issue [#32846](https://github.com/cockroachdb/cockroach/issues/32846), `SET default_int_size` does not take effect until the next statement batch is executed. [#32848][#32848] {% comment %}doc{% endcomment %} -- When creating a [replication zone](https://www.cockroachlabs.com/docs/v19.1/configure-replication-zones), if a field is set to `COPY FROM PARENT`, the field now inherits its value from its parent zone, but any change to the field in the parent zone no longer affects the child zone. [#32861][#32861] {% comment %}doc{% endcomment %} -- Cockroach now supports specifying the matching method for composite [foreign keys](https://www.cockroachlabs.com/docs/v19.1/foreign-key) (a foreign key that includes more than one column) as either `MATCH SIMPLE` or `MATCH FULL`. `MATCH SIMPLE` remains the default. `MATCH FULL` differs from `MATCH SIMPLE` by not allowing the mixing of `NULL` and non-`NULL` values. Only all `NULL` values will not be used to validate a foreign key constraint check or cascading action. `MATCH PARTIAL` is still not supported. For more details see issue [#20305](https://github.com/cockroachdb/cockroach/issues/20305) or https://www.postgresql.org/docs/11/sql-createtable.html.

[#33172][#33172] -- Added support for the `pg_catalog` introspection table `pg_am` for both PostgreSQL versions 9.5 and 9.6, which changed the table significantly. [#33252][#33252] -- Added foreign key checks to kv traces. [#33328][#33328] -- CockroachDB now defines columns `domain_catalog`, `domain_schema` and `domain_name` in `information_schema.columns` (using `NULL` values, since domain types are not yet supported) for compatibility with PostgreSQL clients. [#33267][#33267] -- Attempts to use some PostgreSQL built-in functions that are not yet supported in CockroachDB now cause a clearer error message, and also become reported in [diagnostics reporting](https://www.cockroachlabs.com/docs/v19.1/diagnostics-reporting), if diagnostics reporting is enabled, so as to gauge demand. [#33390][#33390] -- CockroachDB now reports the name (not the value) of unsupported client parameters passed when setting up new SQL sessions in [diagnostics reporting](https://www.cockroachlabs.com/docs/v19.1/diagnostics-reporting), if diagnostics reporting is enabled, to guage demand for additional support. [#33264][#33264] -- CockroachDB now collects statistics for statements executed "internally" (for system purposes). This is meant to facilitate performance troubleshooting. [#32215][#32215] -- CockroachDB now supports associating comments to SQL databases using PostgreSQL's `COMMENT ON DATABASE` syntax. This also provides proper support for pg's `pg_catalog.pg_description` and the `obj_description()` built-in function. [#33057][#33057] {% comment %}doc{% endcomment %} -- CockroachDB now supports associating comments to SQL table columns using PostgreSQL's `COMMENT ON COLUMN` syntax.

- -- Fixed a bug where schema changes could get stuck for 5 minutes when executed immediately after a server restart. [#32988][#32988] -- Fixed a bug with returning dropped unique columns in `DELETE` statements with `RETURNING`. [#33438][#33438] -- Fixed a bug that could cause under-replication or unavailability in 5-node clusters and those using high replication factors. [#32949][#32949] -- Fixed an infinite loop in a low-level scanning routine that could be hit in unusual circumstances. [#33063][#33063] -- CockroachDB no longer reports under-replicated ranges corresponding to replicas that are waiting to be deleted. [#32845][#32845] -- Fixed a possible goroutine leak when canceling queries. [#33130][#33130] -- `CHANGEFEED`s and incremental `BACKUP`s no longer indefinitely hang under an infrequent condition. [#32909][#32909] -- `cockroach node status --ranges` previously listed the count of under-replicated ranges in the `ranges_unavailable` column and the number of unavailable ranges in the `ranges_underreplicated` column. This fixes that mix-up. [#32950][#32950] -- Fixed a panic in the cost-based optimizer during the planning of some queries. [#33183][#33183] -- Cancel requests (via the pgwire protocol) now close quickly with an EOF instead of hanging but still do not cancel the request. [#33202][#33202] -- CockroachDB does not crash upon running `SHOW SESSIONS`, `SHOW QUERIES`, and inspections of some `crdb_internal` tables when certain SQL sessions are issuing internal SQL queries. [#33138][#33138] -- Updated the Zipkin library to avoid deadlock when stopping Zipkin tracing. [#33287][#33287] -- Fixed a panic that could result from not supplying a nullable column in an `INSERT ON CONFLICT ... DO UPDATE` statement. [#33245][#33245] -- Fixed pgwire binary decoding of decimal `NaN` and `NULL` in arrays. [#33295][#33295] -- The `UPSERT` and `INSERT ON CONFLICT` statements now properly check that the user has the `SELECT` privilege on the target table. [#33358][#33358] -- CockroachDB now errors with a fatal exit when data or logging partitions become unresponsive. Previously, the process would remain running, though in an unresponsive state. [#32978][#32978] -- Updated the contextual help for `\h EXPORT` in `cockroach sql` to reflect the actual syntax of the statement. [#33460][#33460] -- `INSERT ON CONFLICT ... DO NOTHING` no longer ignores rows that appear to be duplicate in the `INSERT` operands but are not yet present in the table. These are now properly inserted. [#33320][#33320] -- Prevented a panic with certain queries that use the statement source (square bracket) syntax. [#33537][#33537] -- Previously, CockroachDB did not consider the value of the right operand for `<<` and `>>` operators, resulting in potentially very large results and excessive RAM consumption. This has been fixed to restrict the range of these values to that supported for the left operand. [#33221][#33221] - -Performance improvements
- -- Cross-range disjunctive scans where the result size can be deduced are now automatically parallelized. [#31616][#31616] -- Limited the concurrency of `BACKUP` on nodes with fewer cores to reduce performance impact. [#33277][#33277] -- Index joins, lookup joins, foreign key checks, cascade scans, zig zag joins, and `UPSERT`s no longer needlessly scan over child interleaved tables when searching for keys. [#33350][#33350] - -Doc updates
- -- Updated the [Production Checklist](https://www.cockroachlabs.com/docs/v19.1/recommended-production-settings) with more current hardware recommendations and additional guidance on storage, file systems, and clock synch. [#4153](https://github.com/cockroachdb/docs/pull/4153) -- Expanded the [SQLAlchemy tutorial](https://www.cockroachlabs.com/docs/v19.1/build-a-python-app-with-cockroachdb-sqlalchemy) to provide code for transaction retries and best practices for using SQLAlchemy with CockroachDB.

- -Release Date: {{ include.release_date | date: "%B %-d, %Y" }} - -In addition to SQL language enhancements, general usability improvements, performance improvements, and bug fixes, this release includes several major highlights: - -- [**Follower Reads**](https://www.cockroachlabs.com/docs/v19.1/follower-reads): Enterprise users can now reduce read latencies by allowing queries to perform historical reads of the closest replica of a given piece of data rather than reading from the more distant "leaseholder" replica. To enable follower reads on a query, use the `experimental_follower_read_timestamp()` [built-in function](https://www.cockroachlabs.com/docs/v19.1/functions-and-operators) in conjunction with the `AS OF SYSTEM TIME` clause. -- [**Cost-Based Optimizer**](https://www.cockroachlabs.com/docs/v19.1/cost-based-optimizer): The cost-based optimizer now supports almost all read-only queries (except window functions) and almost all mutations (e.g., `CREATE TABLE AS`, `INSERT`, `UPDATE`, `UPSERT`, `DELETE`). In addition, the cost-based optimizer now reorders up to 4 joins in a query to attempt to find the most performant ordering (via the new `experimental_reorder_joins_limit` [session variable](https://www.cockroachlabs.com/docs/v19.1/set-vars)) and takes advantage of automatic statistics without impacting foreground traffic. Note that statistics are created by default on all indexed columns when a user upgrades to this version. Finally, a query plan cache now saves a portion of the planning time for frequent queries used in the cost-based optimizer. -- [**Change Data Capture**](https://www.cockroachlabs.com/docs/v19.1/change-data-capture): Enterprise users can now create `CHANGEFEED`s that deliver table updates as JSON files to cloud storage endpoints like Google Storage or AWS S3. In addition, all CockroachDB users can now use the core implementation of change data capture, via the new `EXPERIMENTAL CHANGEFEED FOR` statement, to consumes table updates over a streaming Postgres connection. Finally, all `CHANGEFEEDS` now use a new "push" mechanism called _rangefeeds_ to deliver data with increased reliability and lower latency. - -Backward-incompatible changes
- -- The [`CHANGEFEED`](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) `experimental_avro` format is now backward- and forward-compatible with adjacent schemas for the same table. [#34095][#34095] {% comment %}doc{% endcomment %} - -General changes
- -- [Go 1.11.4](https://golang.org/dl/) is now the minimum required version necessary to build CockroachDB. [#33668][#33668] {% comment %}doc{% endcomment %} -- Increased the maximum length of queries in crash reports, to make debugging easier. [#34479][#34479] - -Enterprise edition changes
- -- [`CHANGEFEED`](https://www.cockroachlabs.com/docs/v19.1/create-changefeed)s now experimentally support writing to cloud storage, for easy use with analytics databases. [#33647][#33647] [#34193][#34193] -- The `CHANGEFEED` `envelope=row` option is now deprecated and will be removed in the Fall 2019 release. The default envelope for new changefeeds is now `wrapped`. [#34309][#34309] {% comment %}doc{% endcomment %} -- `CHANGEFEED`s now operate on an end-to-end "push" model, reducing latency of row changes. Some workloads will also see fewer transaction restarts on tables being watched by `CHANGEFEED`s. [#34457][#34457] {% comment %}doc{% endcomment %} -- Added support for standard HTTP proxy environment variables in HTTP and S3 storage. [#34067][#34067] -- Added support for performing sufficiently old historical reads against the closest replicas rather than leaseholders as well as a new `experimental_follower_read_timestamp()` [built-in function](https://www.cockroachlabs.com/docs/v19.1/functions-and-operators), which can be used with [`AS OF SYSTEM TIME`](https://www.cockroachlabs.com/docs/v19.1/as-of-system-time) clauses to generate a timestamp that is likely to be safe for reads from a follower.

- -- [`VALIDATE CONSTRAINT`](https://www.cockroachlabs.com/docs/v19.1/validate-constraint) is now compatible with the new `MATCH FULL` and `MATCH SIMPLE` foreign key semantics and is more performant. [#34365][#34365] {% comment %}doc{% endcomment %} -- Table data is now validated against a newly added [`CHECK`](https://www.cockroachlabs.com/docs/v19.1/check) constraint asynchronously after the transaction commits. [#32504][#32504] {% comment %}doc{% endcomment %} -- `NULL` values are now supported in int and text arrays in the driver protocol. [#33675][#33675] -- CockroachDB now supports transmitting bit array values using the decimal encoding in the low-level client protocol. [#34050][#34050] -- It is now possible to force a reverse scan of a specific index using `table@{FORCE_INDEX=index,DESC}`. [#34075][#34075] {% comment %}doc{% endcomment %} -- Improved the output of [`EXPLAIN`](https://www.cockroachlabs.com/docs/v19.1/explain) for `index-join` and `lookup-join`. [#34138][#34138] {% comment %}doc{% endcomment %} -- `FILTER` expressions are now supported by the cost-based optimizer. [#34077][#34077] {% comment %}doc{% endcomment %} -- [`EXPLAIN (OPT)`](https://www.cockroachlabs.com/docs/v19.1/explain) now has a much shorter output. `EXPLAIN (OPT,VERBOSE)` and `EXPLAIN (OPT,TYPES)` can be used for more verbose output. [#34128][#34128] {% comment %}doc{% endcomment %} -- Using a sequence as a [`SELECT`](https://www.cockroachlabs.com/docs/v19.1/select-clause) target is now supported by the cost-based optimizer. [#33196][#33196] {% comment %}doc{% endcomment %} -- Removed the `2.0-off` and `2.0-auto` modes for the `sql.defaults.distsql` [cluster setting](https://www.cockroachlabs.com/docs/v19.1/cluster-settings). All queries are now run via the newer, distributed SQL engine; queries are still only distributed if appropriate. [#34163][#34163] {% comment %}doc{% endcomment %} -- The `experimental_force_lookup_join` [session variable](https://www.cockroachlabs.com/docs/v19.1/set-vars) has been removed. [#34142][#34142] {% comment %}doc{% endcomment %} -- Added the `experimental_reorder_joins_limit` [session variable](https://www.cockroachlabs.com/docs/v19.1/set-vars), which defaults to `4` and causes the cost-based optimizer to reorder up to 4 joins in a query to attempt to find the most performant ordering. This behavior can be disabled per-session by setting the `experimental_reorder_joins_limit` session variable to 0. [#34549][#34549] {% comment %}doc{% endcomment %} -- Formatting of timestamps as JSON strings has been changed to always use the RFC3339 format instead of Cockroach's customary format. Users can now expect to see a `T` separator instead of a space between the date and time components. [#34412][#34412] {% comment %}doc{% endcomment %} -- Introduced a new top-level statement for an experimental version of [`CHANGEFEED`](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) that doesn't require an enterprise license and that returns results as a stream over the sql connection. [#34386][#34386] {% comment %}doc{% endcomment %} -- The result buffer size can now be controlled on a per-connection basis with the `results_buffer_size` connection string parameter. [#34385][#34385] {% comment %}doc{% endcomment %} -- [`CREATE STATISTICS`](https://www.cockroachlabs.com/docs/v19.1/create-statistics) now runs as a job instead of as a regular SQL statement. [#34279][#34279] {% comment %}doc{% endcomment %} -- [`INT`](https://www.cockroachlabs.com/docs/v19.1/int) values are now stored with microsecond precision instead of nanoseconds. Existing intervals with nanoseconds are no longer able to return their nanosecond part. An existing table `t` with nanoseconds in intervals of column `s` can round them to the nearest microsecond with `UPDATE t SET s = s + '0s'`. Note that this could potentially cause uniqueness problems if the interval is a primary key. [#34202][#34202] {% comment %}doc{% endcomment %} -- Added support for [`AS OF SYSTEM TIME`](https://www.cockroachlabs.com/docs/v19.1/as-of-system-time) clauses in [`BEGIN TRANSACTION`](https://www.cockroachlabs.com/docs/v19.1/begin-transaction) and [`SET TRANSACTION`](https://www.cockroachlabs.com/docs/v19.1/set-transaction) statements, which enables entire read-only transactions to be run against a historical timestamp. This functionality simplifies performing complex analytics against a consistent snapshot of historical data and eases the burden to use historical reads with ORMs which generally make modifying the syntax of generated `SELECT` statements difficult. [#34305][#34305] {% comment %}doc{% endcomment %} -- The behavior of the `now()` [built-in function](https://www.cockroachlabs.com/docs/v19.1/functions-and-operators) inside of historical `SELECT ... AS OF SYSTEM TIME` queries now reflects the historical timestamp at which the query is being run rather than the current clock time when the statement is executed. [#34305][#34305] {% comment %}doc{% endcomment %} -- The `ORDER BY` clause can no longer be used with a `DELETE` statement when there is no `LIMIT` clause present. Sorting the output should instead be done using `SELECT ... FROM [DELETE ...] ORDER BY ...`. [#34303][#34303] {% comment %}doc{% endcomment %} -- Enabled automatic statistics collection. [#34529][#34529] {% comment %}doc{% endcomment %} -- [`DELETE`](https://www.cockroachlabs.com/docs/v19.1/delete), [`UPDATE`](https://www.cockroachlabs.com/docs/v19.1/update), and [`UPSERT`](https://www.cockroachlabs.com/docs/v19.1/upsert) statements are now planned by the cost-based optimizer. [#34522][#34522] {% comment %}doc{% endcomment %} -- The value of `information_schema.columns.character_maximum_column` is set to `NULL` for all integer types, for compatibility with PostgreSQL. [#34182][#34182] {% comment %}doc{% endcomment %} - -Command-line changes
- -- The modified time is now set for entries in [`cockroach debug zip`](https://www.cockroachlabs.com/docs/v19.1/debug-zip) output. [#33714][#33714] {% comment %}doc{% endcomment %} -- Clarified the informational message printed upon running `cockroach start --join`. [#33435][#33435] - -Admin UI changes
- -- Added a debug endpoint listing the hottest ranges by QPS on each node/store. [#33336][#33336] {% comment %}doc{% endcomment %} -- Improved performance of graph detail tooltips when viewing long timespans (e.g., 1 month) [#34032][#34032] -- [`CHANGEFEED`](https://www.cockroachlabs.com/docs/v19.1/create-changefeed) metrics are now exposed in the UI. [#34427][#34427] {% comment %}doc{% endcomment %} - -Bug fixes
- -- Fixed a bug in [`RESTORE`](https://www.cockroachlabs.com/docs/v19.1/restore) that prevented restoring some [`BACKUP`](https://www.cockroachlabs.com/docs/v19.1/backup)s containing previously dropped or truncated interleaved tables. [#34413][#34413] -- Fixed a bug in [`cockroach node status`](https://www.cockroachlabs.com/docs/v19.1/view-node-details) that prevented it from displaying down nodes in the cluster in some circumstances. [#34448][#34448] -- Fixed several related panics in the optimizer related to plan exploration. [#34667][#34667] -- Resolved a cluster degradation scenario that could occur during [`IMPORT`](https://www.cockroachlabs.com/docs/v19.1/import)/[`RESTORE`](https://www.cockroachlabs.com/docs/v19.1/restore) operations, manifested through a high number of pending Raft snapshots. [#33582][#33582] -- Fixed a bug where some comparison operations with constant inputs were not getting folded during query optimization, causing the optimizer to produce sub-optimal plans. [#33597][#33597] -- [Window functions](https://www.cockroachlabs.com/docs/v19.1/window-functions) with non-empty `PARTITION BY` and `ORDER BY` clauses are now handled correctly when invoked via the low-level client protocol. [#33591][#33591] -- Fixed a memory leak around `DEALLOCATE` and `DISCARD` statements that could result in panics with the `unexpectedPerformance improvements
- -- Reduced the network and storage overhead of multi-range transactions. [#33566][#33566] -- A query plan cache now saves a portion of the planning time for frequent queries. [#34454][#34454] -- Transaction record garbage collection requests are now batched on a per range basis to reduce the number of Raft entries in a high-throughput, write-heavy, transactional workload. [#34242][#34242] - -Doc updates
- -- The new [Life of a Distributed Transaction](https://www.cockroachlabs.com/docs/stable/architecture/life-of-a-distributed-transaction) details the path that a query takes through CockroachDB's architecture, starting with a SQL client and progressing all the way to RocksDB (and then back out again). [#4281](https://github.com/cockroachdb/docs/pull/4281) -- Added a [warning about cross-store rebalancing](https://www.cockroachlabs.com/docs/v19.1/start-a-node#store) not working as expected in 3-node clusters with multiple stores per node. [#4320](https://github.com/cockroachdb/docs/pull/4320) -- Updated the [`INT`](https://www.cockroachlabs.com/docs/v19.1/int) documentation to include examples of actual min/max integers supported by each type for easier reference. Also added a description of possible compatibility issues caused by 64-bit integers vs., for example, JavaScript runtimes. [#4317](https://github.com/cockroachdb/docs/pull/4317) -- Documented the `sql.metrics.statement_details.plan_collection.period` [cluster setting](https://www.cockroachlabs.com/docs/v19.1/cluster-settings), which controls how often the logical plan for a fingerprint is sampled (5 minutes by default) on the [**Statements**](https://www.cockroachlabs.com/docs/v19.1/admin-ui-statements-page) page of the Admin UI. [#4316](https://github.com/cockroachdb/docs/pull/4316) -- Added guidance on [removing `UNIQUE` constraints](https://www.cockroachlabs.com/docs/v19.1/constraints#remove-constraints). [#4276](https://github.com/cockroachdb/docs/pull/4276) -- Added a note that when a table that was previously [split](https://www.cockroachlabs.com/docs/v19.1/split-at) is truncated, the table must be pre-split again. [#4274](https://github.com/cockroachdb/docs/pull/4274) -- Updated the [SQL Performance Best Practices](https://www.cockroachlabs.com/docs/v19.1/performance-best-practices-overview#interleave-tables) with caveats around interleaving tables.

- private static FunctionFrom a SQL perspective, a table and its secondary indexes initially map to a single range, where each key-value pair in the range represents a single row in the table (also called the primary index because the table is sorted by the primary key) or a single row in a secondary index. As soon as that range reaches 64 MiB in size, it splits into two ranges. This process continues for these new ranges as the table and its indexes continue growing. -**Replica** | CockroachDB replicates each range (3 times by default) and stores each replica on a different node. -**Leaseholder** | For each range, one of the replicas holds the "range lease". This replica, referred to as the "leaseholder", is the one that receives and coordinates all read and write requests for the range.
Unlike writes, read requests access the leaseholder and send the results to the client without needing to coordinate with any of the other range replicas. This reduces the network round trips involved and is possible because the leaseholder is guaranteed to be up-to-date due to the fact that all write requests also go to the leaseholder. -**Raft Leader** | For each range, one of the replicas is the "leader" for write requests. Via the [Raft consensus protocol](replication-layer.html#raft), this replica ensures that a majority of replicas (the leader and enough followers) agree, based on their Raft logs, before committing the write. The Raft leader is almost always the same replica as the leaseholder. -**Raft Log** | For each range, a time-ordered log of writes to the range that its replicas have agreed on. This log exists on-disk with each replica and is the range's source of truth for consistent replication. diff --git a/src/current/_includes/v19.1/misc/beta-warning.md b/src/current/_includes/v19.1/misc/beta-warning.md deleted file mode 100644 index 107fc2bfa4b..00000000000 --- a/src/current/_includes/v19.1/misc/beta-warning.md +++ /dev/null @@ -1,3 +0,0 @@ -{{site.data.alerts.callout_danger}} -**This is a beta feature.** It is currently undergoing continued testing.

-### Configure Alertmanager
-
-Active monitoring helps you spot problems early, but it is also essential to send notifications when there are events that require investigation or intervention. This section shows you how to use [Alertmanager](https://prometheus.io/docs/alerting/alertmanager/) and CockroachDB's starter [alerting rules](https://github.com/cockroachdb/cockroach/blob/master/cloud/kubernetes/prometheus/alert-rules.yaml) to do this.
-
-1. Download our alertmanager-config.yaml configuration file:
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ curl -OOOOOOOOO \
- https://raw.githubusercontent.com/cockroachdb/cockroach/master/cloud/kubernetes/prometheus/alertmanager-config.yaml
- ~~~
-
-2. Edit the `alertmanager-config.yaml` file to [specify the desired receivers for notifications](https://prometheus.io/docs/alerting/configuration/#receiver). Initially, the file contains a placeholder web hook.
-
-3. Add this configuration to the Kubernetes cluster as a secret, renaming it to `alertmanager.yaml` and labelling it to make it easier to find:
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl create secret generic alertmanager-cockroachdb \
- --from-file=alertmanager.yaml=alertmanager-config.yaml
- ~~~
-
- ~~~
- secret/alertmanager-cockroachdb created
- ~~~
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl label secret alertmanager-cockroachdb app=cockroachdb
- ~~~
-
- ~~~
- secret/alertmanager-cockroachdb labeled
- ~~~
-
- {{site.data.alerts.callout_danger}}
- The name of the secret, `alertmanager-cockroachdb`, must match the name used in the `altermanager.yaml` file. If they differ, the Alertmanager instance will start without configuration, and nothing will happen.
- {{site.data.alerts.end}}
-
-4. Use our [`alertmanager.yaml`](https://github.com/cockroachdb/cockroach/blob/master/cloud/kubernetes/prometheus/alertmanager.yaml) file to create the various objects necessary to run an Alertmanager instance, including a ClusterIP service so that Prometheus can forward alerts:
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl apply \
- -f https://raw.githubusercontent.com/cockroachdb/cockroach/master/cloud/kubernetes/prometheus/alertmanager.yaml
- ~~~
-
- ~~~
- alertmanager.monitoring.coreos.com/cockroachdb created
- service/alertmanager-cockroachdb created
- ~~~
-
-5. Verify that Alertmanager is running:
-
- 1. Port-forward from your local machine to the pod running Alertmanager:
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl port-forward alertmanager-cockroachdb-0 9093
- ~~~
-
- 2. Go to http://localhost:9093 in your browser. The screen should look like this:
-
- 
-
-6. Ensure that the Alertmanagers are visible to Prometheus by opening http://localhost:9090/status. The screen should look like this:
-
- 
-
-7. Add CockroachDB's starter [alerting rules](https://github.com/cockroachdb/cockroach/blob/master/cloud/kubernetes/prometheus/alert-rules.yaml):
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl apply \
- -f https://raw.githubusercontent.com/cockroachdb/cockroach/master/cloud/kubernetes/prometheus/alert-rules.yaml
- ~~~
-
- ~~~
- prometheusrule.monitoring.coreos.com/prometheus-cockroachdb-rules created
- ~~~
-
-8. Ensure that the rules are visible to Prometheus by opening http://localhost:9090/rules. The screen should look like this:
-
- 
-
-9. Verify that the `TestAlertManager` example alert is firing by opening http://localhost:9090/alerts. The screen should look like this:
-
- 
-
-10. To remove the example alert:
-
- 1. Use the `kubectl edit` command to open the rules for editing:
-
- {% include copy-clipboard.html %}
- ~~~ shell
- $ kubectl edit prometheusrules prometheus-cockroachdb-rules
- ~~~
-
- 2. Remove the `dummy.rules` block and save the file:
-
- ~~~
- - name: rules/dummy.rules
- rules:
- - alert: TestAlertManager
- expr: vector(1)
- ~~~

-### Topology
-
-You'll start with a 3-node CockroachDB cluster in a single Google Compute Engine (GCE) zone, with an extra instance for running a client application workload:
-
-
-
-{{site.data.alerts.callout_info}}
-Within a single GCE zone, network latency between instances should be sub-millisecond.
-{{site.data.alerts.end}}
-
-You'll then scale the cluster to 9 nodes running across 3 GCE regions, with an extra instance in each region for a client application workload:
-
-
-
-To reproduce the performance demonstrated in this tutorial:
-
-- For each CockroachDB node, you'll use the [`n1-standard-4`](https://cloud.google.com/compute/docs/machine-types#standard_machine_types) machine type (4 vCPUs, 15 GB memory) with the Ubuntu 16.04 OS image and a [local SSD](https://cloud.google.com/compute/docs/disks/#localssds) disk.
-- For running the client application workload, you'll use smaller instances, such as `n1-standard-1`.
-
-### Schema
-
-Your schema and data will be based on our open-source, fictional peer-to-peer ride-sharing application,[MovR](https://github.com/cockroachdb/movr).
-
-
-
-A few notes about the schema:
-
-- There are just three self-explanatory tables: In essence, `users` represents the people registered for the service, `vehicles` represents the pool of vehicles for the service, and `rides` represents when and where users have participated.
-- Each table has a composite primary key, with `city` being first in the key. Although not necessary initially in the single-region deployment, once you scale the cluster to multiple regions, these compound primary keys will enable you to [geo-partition data at the row level](partitioning.html#partition-using-primary-key) by `city`. As such, this tutorial demonstrates a schema designed for future scaling.
-- The [`IMPORT`](import.html) feature you'll use to import the data does not support foreign keys, so you'll import the data without [foreign key constraints](foreign-key.html). However, the import will create the secondary indexes required to add the foreign keys later.
-- The `rides` table contains both `city` and the seemingly redundant `vehicle_city`. This redundancy is necessary because, while it is not possible to apply more than one foreign key constraint to a single column, you will need to apply two foreign key constraints to the `rides` table, and each will require city as part of the constraint. The duplicate `vehicle_city`, which is kept in sync with `city` via a [`CHECK` constraint](check.html), lets you overcome [this limitation](https://github.com/cockroachdb/cockroach/issues/23580).

-### Important concepts
-
-To understand the techniques in this tutorial, and to be able to apply them in your own scenarios, it's important to first understand [how reads and writes work in CockroachDB](architecture/reads-and-writes-overview.html). Review that document before getting started here.

-For this service, the most effective technique for improving read and write latency is to [geo-partition](partitioning.html) the data by city. In essence, this means changing the way data is mapped to ranges. Instead of an entire table and its indexes mapping to a specific range or set of ranges, all rows in the table and its indexes with a given city will map to a range or set of ranges. Once ranges are defined in this way, we can then use the [replication zone](configure-replication-zones.html) feature to pin partitions to specific locations, ensuring that read and write requests from users in a specific city do not have to leave that region.
