Subject [jira] [Commented] (HBASE-15179) Cell/DBB end-to-end on the write-path
Date Thu, 06 Apr 2017 05:01:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15958289#comment-15958289

Anoop Sam John commented on HBASE-15179:
----------------------------------------

We dont need BC for the write path.  Ya we will need some doc on how to enable it.  Let me
write as a combined release notes here. (Though individual jiras say on that item how to do).
  Let me see the google docs.. May be some comments yet to close and some cleanup after the
final patches went in.  (I did some parts of that few weeks back).
Sure blog is coming soon..  Taking some perf readings and charts for that.  Am on that this
week.

> Umbrella jira to make the HBase write path off heap E2E. We have to make sure we have
Cells flowing in entire write path. Starting from request received in RPC layer, till the
Cells get flushed out as HFiles, we have to keep the Cell data off heap.
