Subject [jira] [Commented] (HBASE-10719) Cell interface may need a ByteBuffer rather than a byte[]
Date Fri, 14 Mar 2014 18:10:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13935366#comment-13935366

Nick Dimiduk commented on HBASE-10719:

Shouldn't we consider ByteBuffers for values so that we can work toward an entirely off-heap
data pathway? This will enable larger value blobs (10's - 100's of MB) for users and open
the way for (closer to) zero copy pipeline.

> The byte[] backing a cell may be off heap also.  In such a case having a byte[] may require
a copy offheap to on heap.  So better to have ByteBuffer backing a Cell.
