Subject [jira] [Commented] (HBASE-6659) Port HBASE-6508 Filter out edits at log split time
Date Wed, 29 Aug 2012 22:55:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13444508#comment-13444508

Ted Yu commented on HBASE-6659:

bq. or we could put it in a data structure apart from serverload
Do we have a route through which such data structure can be channeled to master nowadays ?

bq. out of metrics w/ master pulling the info when its interested in particular
The use case for this feature is that log splitters may request sequence Ids in a short period
of time. I am not sure if I understand the above comment enough in this context.

I agree with Stack's analysis on using zookeeper. In a large cluster under heavy write load,
sufficient experiment / profiling is needed to justify the approach.

Again, the reason I came with the port was that I found this feature very helpful, even if
HBASE-5699 is implemented.
I think the patch didn't introduce fresh design deficiency.

I can address Stack's other comments in the next patch.

When there is good alternative to retiring heartbeat, all the payload can be moved in one
