Subject [jira] Commented: (CASSANDRA-1141) remove HintedHandOffManager.deliverAllHints
Date Fri, 28 May 2010 17:02:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12873057#action_12873057

Jonathan Ellis commented on CASSANDRA-1141:
-------------------------------------------

We should also move the flush-then-compact code from dAH to dHTE, and give it Integer.MaxValue
as gcBefore since there is no need to age out tombstones gracefully.

> deliverAllHints seems to be a "just in case we miss the onAlive signal to send hints
over," but the constant scanning of the hint rows it generates is extremely painful.
> I'd like to do 3 things here:
> 1. test that, if node X and Y are in the cluster, and Y goes down, then X goes down,
then Y comes back up, then X comes back up [with enough time for each change that FD recognizes
it], that X gets deliverHintsToEndpoint called for Y.  I think it will, but we should test
to be sure.
> 2. remove HHOM.deliverAllHints
> 3. expose HHOM.deliverHintsToEndpoint to jmx so it can be manually invoked, Just In Case
