-------------------------------
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.
