Subject [jira] [Commented] (CASSANDRA-13789) Reduce memory copies and object creations when acting on ByteBufs
Date Wed, 27 Sep 2017 14:03:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16182610#comment-16182610
] 

Jason Brown commented on CASSANDRA-13789:
-----------------------------------------

[~Stefania] you are totally right. In fact, I even had to deal with debugging that same problem
once when working on CASSANDRA-12229, and it was nasty to debug (not sure how i missed that
in review :-/ ).

Let's give [~norman] a day or two to respond with any comments, else, I'll go ahead and revert
that part.
