Subject [jira] [Commented] (CASSANDRA-4075) Dropped keyspaces and cfs do not get deleted
Date Fri, 23 Mar 2012 13:53:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13236598#comment-13236598
] 

Jonathan Ellis commented on CASSANDRA-4075:
-------------------------------------------

bq. can we get a backport of it to 0.8.x, particularly 0.8.1?

No, this isn't really back-portable since it was a total rewrite of the sstable deletion code,
from being based on PhantomReferences triggered by GC, to manual reference counting.

bq. just tested a full gc on both 0.8.10 and 0.8.1 after waiting rpc_timeout seconds and the
sstables that were marked as compacted through the drop command did clear.

Good, that's what we'd expect then.

> Tested in 0.8.10, reported in 0.8.1.
> Dropped keyspaces and column families have their sstables marked as Compacted, but will
not disappear, even on restart. 
> Worked correctly in 1.0.8 where the sstables get deleted almost immediately following
the column family drop.
