Subject [jira] [Commented] (CASSANDRA-13789) Reduce memory copies and object creations when acting on ByteBufs
Date Thu, 28 Sep 2017 06:03:01 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16183709#comment-16183709
] 

Norman Maurer commented on CASSANDRA-13789:
-------------------------------------------

[~jasobrown] [~Stefania] my exception was that caller of this methods ensure that there will
be no "concurrent" access to the underlying object and so duplicate it if necessary. If this
is not true then yes this needs to be changed. Just let me know and I will take care (happy
to write a patch).

> There are multiple "low-hanging-fruits" when it comes to reduce memory copies and object
allocations when acting on ByteBufs.
