[jira] Commented: (CASSANDRA-1792) Reduce byte array copies when using serialization/deserialization helper methods

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12965345#action_12965345 ] 

Jonathan Ellis commented on CASSANDRA-1792:
-------------------------------------------

i don't know enough about thrift internals to tell if there is potential for unflushed data to be in the TProtocol/TIOStreamTransport pipeline this way.  if we can rule that out then it looks good to me.

> From looking at CASSANDRA-1765 it seems FBUtilities serialize and deserialize methods unnecessarily make byte[] copies due to the way TSerializer is being used.  
> This can be changed to avoid making any copies. 
> These methods are only used in a couple serializers so not a big issue at this point.
