[jira] [Created] (FLINK-6337) Remove the buffer provider from
PartitionRequestServerHandler
zhijiang created FLINK-6337:
-------------------------------
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.
