[jira] [Commented] (CASSANDRA-5051) Allow automatic cleanup after gc_grace

["Jeff Jirsa (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14731813#comment-14731813 ] 

Jeff Jirsa commented on CASSANDRA-5051:
---------------------------------------

I once again find myself wishing this existed, I've read through the comments and it looks like there's nearly unanimous consensus that this is a nice thing to have, but progress was paused waiting on 2.1 streaming. With 3.0 heading into beta, is now a good time to nudge this? Or are there more blockers on the horizon? 

// [~cburroughs] given the choice between A, B, and C, I'd love C, because in 5 years of operating in production, I've never once had to go back and pull a replica from a node that no longer owned it because I somehow messed up ownership so bad I didn't have a real replica elsewhere. It's 2015, snapshots are cheaper than ever, cleanup should be more frequent.

> When using vnodes, after adding a new node you have to run cleanup on all the machines, because you don't know which are affected and chances are it was most if not all of them.  As an alternative to this intensive process, we could allow cleanup during compaction if the data is older than gc_grace (or perhaps some other time period since people tend to use gc_grace hacks to get rid of tombstones.)
