    Hi @uce , I have submitted the modifications of `createReadView`, and the tests and IT
have passed in my private travis.  I checked the failed test `HistoryServerTest.testFullArchiveLifecycle`
on this travis and it seems no related to my pull request. I run it several times separately
again and all are passed.

> 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.
