Installation

To install Trino, add the following to the kfctl file:

- kustomizeConfig:
    parameters:
    - name: s3_endpoint_url
      value: s3.odh.com
    - name: s3_credentials_secret
      value: s3-credentials
    repoRef:
      name: manifests
      path: trino
  name: trino

Overlays

Trino component comes with 1 overlay.

storage-class

Customizes Trino to use a specific StorageClass for PVCs, see storage_class parameter.

Parameters

There are 15 parameters exposed via KFDef.

storage_class

Name of the storage class to be used for PVCs created by Trino component. This requires storage-class overlay to be enabled as well to work.

s3_endpoint_url

HTTP endpoint exposed by your S3 object storage solution which will be made available to Trino as the default S3 filesystem location. This parameter is required.

s3_credentials_secret

Along with s3_endpoint_url this parameter configures the Trino's access to S3 object storage. Setting this parameter to any name of local Openshift/Kubernetes Secret resource name would allow Thift Server to consume S3 credentials from it. The secret of choice must contain AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and BUCKET variables. If not set, credentials from aws-secret will be used instead.

trino_environment

This is a parameter to specify the node.environment property from node.properties file, which specifies to all trino nodes the name of the environment. For more information, see the Trino documentation

trino_db_database_name

This parameter will configure the Trino database name. All Hive Metastore information is stored in this database. If not set, trino will be used instead.

trino_db_secret

Along with trino_db_database_name this parameter configures the Hive Metastore database. Setting this parameter to any name of local Openshift/Kubernetes Secret resource name would allow Thift Server to consume S3 credentials from it. The secret of choice must contain database-user and database-password keys. If not set, credentials from trino-db-secret will be used instead.

hive_metastore_cpu_request

This parameter will configure the CPU request for Hive Metastore. If not set, the default value 1 will be used instead.

hive_metastore_cpu_limit

This parameter will configure the CPU limit for Hive Metastore. If not set, the default value 1 will be used instead.

hive_metastore_memory_request=

This parameter will configure the Memory request for Hive Metastore. If not set, the default value 4Gi will be used instead.

hive_metastore_memory_limit

This parameter will configure the Memory limit for Hive Metastore. If not set, the default value 4Gi will be used instead.
