Thanks Thibaut, believe it or not, it does. :) Is your use case a typical web app or something like a scientific/data mining app? I ask because I'm wondering how you have managed to deal with the stop-the-world garbage collection issues that seems to hit most clusters that have significant load and cause application timeouts. Have you found that cassandra scales in read/write capacity reasonably well as you add nodes? Also, you may also want to backport these fixes at a minimum? * reduce memory use during streaming of multiple sstables (CASSANDRA-2301) * update memtable_throughput to be a long (CASSANDRA-2158)
