Subject [jira] [Commented] (HBASE-10772) Use ByteRanges instead of ByteBuffers in BlockCache
Date Wed, 26 Mar 2014 16:34:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13948069#comment-13948069
] 

Andrew Purtell commented on HBASE-10772:
----------------------------------------

bq. Currently we don't have any offheap based BR. So if we try to create a BR that is backed
by DBB and to ensure the current behaviour works of BR pools etc we may need such things in
BR also

I suggest trying a BR backed by a DBB and adding only the minimum of what is needed.

> Try replacing the BBs with Byte Ranges in Block cache.  See if this can be done in a
pluggable way.
