 Description   

In PM-1944 a cluster-wide configuration parameter was added to provide control on how much time can pass after the change event occurrence when the system can purge any state required to provide pre- and post-images for the change event. Implement propagation throughout the cluster and persistence aspects of that parameter by leveraging mechanisms provided by PM-2502 (Mechanism for Specifying Cluster-Wide Configuration Options).

Additional scope:

  • Enable the feature flag that guards the configuration parameter, so the time-based change stream pre-image retention policy becomes accessible to the users.
  • Create a task to remove the feature flag referred to above.

The parameter was introduced by SERVER-58692.
