Subject [jira] [Commented] (CASSANDRA-5051) Allow automatic cleanup after gc_grace
Date Thu, 04 Apr 2013 18:17:16 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13622607#comment-13622607

Jonathan Ellis commented on CASSANDRA-5051:
-------------------------------------------

Does 0004 fail if you remove the pending ranges code?  It looks to me like it might not. 
(Couldn't actually try it since I ran into rebase problems.)

> 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.)
