DROP PIPELINE

The DROP PIPELINE clause deletes a pipeline from your SingleStore cluster. If the pipeline is currently running, it will stop it before deleting it.

Syntax

DROP PIPELINE [IF EXISTS] pipeline_name;

Remarks

  • After a pipeline has been dropped, any data related to the pipeline will also be deleted from the information_schema tables associated with the Pipelines feature.

  • This command causes implicit commits. Refer to COMMIT for more information.

  • The background tasks of a pipeline runs in its resource pool. Therefore, a resource pool used by a pipeline cannot be dropped.

    For more information on resource pools, see Set Resource Limits.

  • Refer to the Permission Matrix for the required permission.

Caution

If a pipeline is dropped and recreated, the pipeline will start reading from the earliest offset in the data source, once the pipeline is started. This may cause duplicate records to be inserted into the destination table(s).

Example

SHOW PIPELINES;
+-------------------------+---------+
| Pipelines_in_mydatabase | State   |
+-------------------------+---------+
| quickstart_kafka        | Running |
+-------------------------+---------+
DROP PIPELINE quickstart_kafka;
Query OK, 0 rows affected (0.00 sec)
SHOW PIPELINES;
Empty set (0.00 sec)
