Jonathan Ellis updated CASSANDRA-2673:
--------------------------------------
Attachment: 2673.txt
patch to move the truncation operation to CompactionManager instead of
postFlushExecutor. (Not sure what the thinking was there, to be honest. Which
may mean it's something subtle I'm missing now, or maybe just that I was
smoking crack when I wrote that code originally. CASSANDRA-531, the original
truncate ticket, doesn't shed any light here.)
