Cleaning Up Old Messages in Workflow/Cluster
If I understand stuff correctly Workflow/Cluster (in Cluster case only persisted messages/primary key etc) stores messages/steps progress etc inside of database for correct working. Also if I start a workflow again with the same idempotency key - I get previous result. Generally speaking it's super usefull. I'm wondering one thing - is there some way/path for cleaning up old messages that are for sure no longer needed?
