Subject [jira] [Commented] (HBASE-9834) Minimize byte[] copies for 'smart' clients
Date Tue, 29 Oct 2013 01:43:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13807580#comment-13807580

Jesse Yates commented on HBASE-9834:
------------------------------------

Other thing I'd like to add is to actually be able to pass in an ImmutableBytesWritable to
a mutation for the row, so we could completely reuse the bytes everywhere. Might fit here,
but thinking about just doing in a follow up.

> 'Smart' clients (e.g. phoenix) that have in-depth knowledge of HBase often bemoan the
extra byte[] copies that must be done when building multiple puts/deletes. We should provide
a mechanism by which they can minimize these copies, but still remain wire compatible.
