[jira] [Created] (FLINK-10332) Move data available notification in PipelinedSubpartition out of the synchronized block

Nico Kruber created FLINK-10332:
-----------------------------------

             Summary: Move data available notification in PipelinedSubpartition out of the synchronized block
                 Key: FLINK-10332
                 URL: https://issues.apache.org/jira/browse/FLINK-10332
             Project: Flink
          Issue Type: Sub-task
          Components: Network
    Affects Versions: 1.6.0, 1.5.3, 1.5.2, 1.5.1, 1.5.0, 1.7.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


Currently, calls to {{PipelinedSubpartition#notifyDataAvailable();}} are unnecessarily executed inside a {{synchronized (buffers)}} block which may lead to lock contention.
