Reduce number of flush requests to the network stack

    XMLWordPrintableJSON

Details

    Description

      With the re-design of the record writer interaction with the result(sub)partitions, flush requests can currently pile up in these scenarios:

      • a previous flush request has not been completely handled yet and/or is still enqueued or
      • the network stack is still polling from this subpartition and doesn't need a new notification

      These lead to increased notifications in low latency settings (low output flusher intervals) which can be avoided.
