Subject [jira] [Commented] (HBASE-12297) Support DBB usage in Bloom and HFileIndex area
Date Tue, 28 Oct 2014 20:57:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14187446#comment-14187446

stack commented on HBASE-12297:
-------------------------------

I suppose the Interface forces us create an array here?

+      checksumObject.update(ByteBufferUtils.toBytes(hdr, 0, hdrSize), 0, hdrSize);

Its going to be slow indexing through each byte of a DBB.

That is good you do the hasArray check first.
