[jira] [Commented] (HBASE-16783) Use ByteBufferPool for the header and message during Rpc response

["Anoop Sam John (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-16783?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15551894#comment-15551894 ] 

Anoop Sam John commented on HBASE-16783:
----------------------------------------

Header will be of smaller size and even the message (am considering we will be doing the Codec based Cellblocking).  It might be a waste of 64 KB buffers for much smaller size?  Do we have a size check before deciding even for the cell block creation also? That we have to use the BBs?  May be we need a small sized buffers pool (different one) also?

> With ByteBufferPool in place we could avoid the byte[] creation in RpcServer#createHeaderAndMessageBytes and try using the Buffer from the pool rather than creating byte[] every time.
