SEP-22: Container Placements in Samza Prateek Maheshwari maintaining some in-memory state with Container Placement Service Who's responsibility is it to dedup requests? CPH or CPS? If CPH, why is the state kept in CPS? Sanil Jain This is old, CPH is stateless this is the duty of Container Placement Service (CPS) removing it View comment • Like Prateek Maheshwari need to be deleted How / where does this happen? E.g., do you have a default TTL + timestamp in the control message where CPH rejects + deletes them if they're too old? Sanil Jain Messages can be deleted across restarts i.e on start-up.  In addition the client side tool will have ability to delete messages by directly writing to metastore View comment • Like Prateek Maheshwari No need to build Authentication since AM runs on hosts which are blacklisted for anyone except the Samza Team LI specific detail, not true in general. Sanil Jain Changing it here! thanks! View comment • Like View page
