Subject [jira] [Commented] (CASSANDRA-3181) Compaction fails to occur
Date Tue, 13 Sep 2011 20:11:08 GMT

Sylvain Lebresne commented on CASSANDRA-3181:
---------------------------------------------

bq. . So I think repair was blocking minors

repair should be on its own executor now, so it shouldn't block minors.

bq. a compaction failed unexpectedly

hum, a compaction failing shouldn't stop other compactions. Otherwise this is worth fixing.

bq. I'm pretty sure that we're just looking at a problem where a server restarts and there
is no more activity triggering a flush

If that's the case, then is there really much we want to do ? And even if we want, we should
move that to 1.0.1. Just want to make sure this doesn't hide a real, unknown,  problem.

> Compaction just stops running at some point.  To repro, insert like 20M rows with a 1G
heap and you'll get around 1k sstables.  Restarting doesn't help, you have to invoke a major
to get anything to happen.
