-------------------------------

             Summary: Remove the buffer provider from PartitionRequestServerHandler
                 Key: FLINK-6337
                 URL: https://issues.apache.org/jira/browse/FLINK-6337
             Project: Flink
          Issue Type: Improvement
          Components: Network
            Reporter: zhijiang
            Assignee: zhijiang
            Priority: Minor


Currently, {{PartitionRequestServerHandler}} will create a {{LocalBufferPool}} when the channel is registered. The {{LocalBufferPool}} is only used to get segment size for creating read view in {{SpillableSubpartition}}, and the buffers in the pool will not be used all the time, so it will waste the buffer resource of global pool.

We would like to remove the {{LocalBufferPool}} from the {{PartitionRequestServerHandler}}, and the {{LocalBufferPool}} in {{ResultPartition}} can also provide the segment size for creating sub partition view.
