SQL Server operational considerations
Operational considerations when using MS SQL Reader
If you will no longer use an app in which MS SQL Reader's Auto Disable Table CDC property is False, when stopping it for the last time, do the following in order to delete the tables that will no longer be used for CDC (see Learn / SQL / SQL Server / Change Data Capture Tables (Transact-SQL)):
Stop and undeploy the application.
In the Flow Designer, edit the MS SQL Reader, set Auto Disable Table CDC to True, and save the change.
Redeploy and start the application.
Stop, undeploy, and drop the application.
