DeleteQualityFollower -

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, transform, and load (ETL). Then, Data Quality automatically blocks the tasks that involve dirty data to stop dirty data from spreading downstream. This way, you can prevent tasks from producing unexpected dirty data that affects the smooth running of tasks and business decision-making. You can go to the Manage Subscriptions page to add subscribers for a partition filter expression. When the monitoring rule that is created based on the partition filter expression is triggered, the subscribers can receive notifications and troubleshoot errors at the earliest opportunity. For more information, see Configure monitoring rules.
