---------------------------------
[~uce], do you think it makes sense to remove the buffer provider from server
handler? I wonder there would be future plans conflicted with it.
If not, I will submit the pull request for it. Thank you!

> 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.
