I thought setcompactionthroughput just adjusted the compaction speed when the server is online? I'm looking for something like a scrub (which as far as I know does not do this) that will compat the tables appropriately while the Cassandra daemon is down.
And I know why I've got heap pressure--the cluster's data sources are growing faster than the cluster is (and was designed for). That's a somewhat longer-term fix involving new hardware, I think. -- Josh From: Robert Coli <rc...@eventbrite.com<mailto:rc...@eventbrite.com>> Reply-To: "user@cassandra.apache.org<mailto:user@cassandra.apache.org>" <user@cassandra.apache.org<mailto:user@cassandra.apache.org>> Date: Monday, October 13, 2014 at 1:49 PM To: "user@cassandra.apache.org<mailto:user@cassandra.apache.org>" <user@cassandra.apache.org<mailto:user@cassandra.apache.org>> Subject: Re: Compact tables when offline On Mon, Oct 13, 2014 at 8:27 AM, Sholes, Joshua <joshua_sho...@cable.comcast.com<mailto:joshua_sho...@cable.comcast.com>> wrote: My question is this: Is there a command that I'm missing that I could use to force that node to do compaction on those tables and clean up some of the thousands of 100-500byte tables while Cassandra itself is offline? I've got plenty of disk space so that's not an issue. nodetool setcompactionthroughput 0 But if you have that many tiny files, you probably have serious heap pressure and are flushing all the time and should figure out why. =Rob http://twitter.com/rcolidba
