Thanks, this does look like what I'm experiencing. Can someone post a walkthrough ? The README and the sstablesplit script don't seem to cover it use in any detail.

Take a look at the very recent thread called 'Alternate "major compaction"'. There are some ideas in there about splitting up a large SSTable. http://www.mail-archive.com/user@cassandra.apache.org/msg30956.html On 07/17/2013 04:17 PM, Langston, Jim wrote: Hi all, Is there a way to get an SSTable to a smaller size ? By this I mean that I currently have an SSTable that is nearly 1.2G, so that subsequent SSTables when they compact are trying to grow to that size. The result is that when the min_compaction_threshold reaches it value and a compaction is needed, the compaction is taking a long time as the file grows (it is currently at 52MB and takes ~22s to compact). I'm not sure how the SSTable initially grew to its current size of 1.2G, since the servers have been up for a couple of years. I hadn't noticed until I just upgraded to 1.2.6, but now I see it affects everything. Jim -- Colin Blower Software Engineer Barracuda Networks Inc. +1 408-342-5576 (o)
