    Problem Short description Description Steps to reproduce

    Activity Stream

    PRB1858894

    KB2027692

    		 Application Programming Interface (API), Now Platform, and GraphQL are slow due to the Table Cleaner being throttled causing heavy replication lag

    API, Now Platform, and GraphQL calls are slow specifically because of the Table Cleaner on sys_activity shards. ​Using Instant Alter added an index, and as a result, all records were replicated with the load causing replication lag. When replication lag is detected, Table Cleaners are throttled, which can exacerbate the amount of data that is being replicated and cause timeouts. Timeouts are caused by the Table Cleaner running synchronously in the Activity Stream load request.
