 | [`tidb_pipelined_dml_resource_policy`](/system-variables.md#tidb_pipelined_dml_resource_policy-new-in-v900) | Newly added | Controls the resource usage policy for [Pipelined DML](/pipelined-dml.md). It takes effect only when [`tidb_dml_type`](/system-variables.md#tidb_dml_type-new-in-v800) is set to `bulk`. |
 | [`tidb_accelerate_user_creation_update`](/system-variables.md/#tidb_accelerate_user_creation_update-new-in-v900)| Newly added | Improves the performance of creating and modifying users in scenarios with hundreds of thousands to millions of users. |
 | [`tidb_max_dist_task_nodes`](/system-variables.md/#tidb_max_dist_task_nodes-new-in-v900)| Newly added | Controls the maximum number of TiDB nodes available for the Distributed eXecution Framework (DXF) tasks. The default value is `-1`, which enables automatic mode. In this mode, the system automatically selects an appropriate number of nodes. |
-| [`tidb_workload_repository_active_sampling_interval`](/system-variables.md#tidb_workload_repository_active_sampling_interval-new-in-v900) | Newly added | Controls the sampling interval for the [Workload Repository](/workloadrepo.md)'s Time-based Sampling Process. |
-| [`tidb_workload_repository_dest`](/system-variables.md#tidb_workload_repository_dest-new-in-v900)| Newly added | Controls the destination of the [Workload Repository](/workloadrepo.md. The default value is `''`, which means to disable the workload repository. The value `'table'` enables the workload repository to write data into TiKV.| 
-| [`tidb_workload_repository_retention_days`](/system-variables.md#tidb_workload_repository_retention_days-new-in-v900) | Newly added | Controls the number of days that [Workload Repository](/workloadrepo.md) data is retained. |
-| [`tidb_workload_repository_snapshot_interval`](/system-variables.md#tidb_workload_repository_snapshot_interval-new-in-v900) | Newly added | Controls the sampling interval for the [Workload Repository](/workloadrepo.md)'s Snapshot Sampling Process. |
