[jira] [Created] (FLINK-16848) Improve the performance of the RecordsWithSplitIds queue.

Jiangjie Qin created FLINK-16848:
------------------------------------

             Summary: Improve the performance of the RecordsWithSplitIds queue.
                 Key: FLINK-16848
                 URL: https://issues.apache.org/jira/browse/FLINK-16848
             Project: Flink
          Issue Type: Sub-task
            Reporter: Jiangjie Qin


Currently there is just one queue in the SourceReader which may become a performance bottleneck due to lock contention when there are many SplitFetcher threads. This ticket is supposed to improve the performance.
