[jira] [Updated] (CASSANDRA-3116) Compactions can (seriously )delay schema migrations

     [ https://issues.apache.org/jira/browse/CASSANDRA-3116?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis updated CASSANDRA-3116:
--------------------------------------

    Fix Version/s: 1.1

agreed that this sucks.  would like to switch to some kind of test-and-set safety for compaction vs migration instead.  not immediately obvious to me how to do this.

> A compaction lock is acquired when dropping keyspaces or column families which will cause the schema migration to block if a compaction is in progress.
