The SeekableStreamSupervisor fetches the task payloads for every active task in its datasource twice every RunNotice. In large clusters, this may cause the RunNotice to take a long time when it may be able to complete within a couple of seconds otherwise. If there are hundreds of supervisors, there are `4 * supervisors` calls to the metadata store every minute to fetch all the active datasource task payloads. This change can help reduce the load on the db significantly in such cases. -- This is an automated message from the Apache Git Service.
