Deletes a subscriber of a partition filter expression. The deleted subscriber no longer receives notifications even if a subscribed monitoring rule of Data Quality is triggered.

In Data Quality, you must configure monitoring rules based on a partition filter expression. Data Quality uses these rules to detect changes in source data and dirty data generated during the process of extract, transformation, load (ETL). Thereby, Data Quality automatically blocks the nodes that involve dirty data to stop dirty data from spreading downstream. This prevents nodes from producing unexpected dirty data that affects normal use and business decisions. You can go to the Manage Subscriptions page to add subscribers for a partition filter expression. When the monitoring rule described by the partition filter expression is triggered, the subscribers can receive notifications and troubleshoot errors in a timely manner. For more information, see Configure monitoring rules for MaxCompute.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
