I believe the decommission call is blocking in both .6 and .7, so once it returns it should have completed. On Wed, Dec 8, 2010 at 3:10 AM, Jake Maizel j...@soundcloud.com wrote: Hello, Is there a definitive way to tell if a Decommission operation has completed, such as a log message similar

Interesting idea, . If it is like dividing the entire load on the system by 6, so if the effective load is still the same and used SSD's for commit volume we could get away with 1 commitlog SSD. Even if these 6 instances can handle 80% of the load (compared to 1 on this machine), that might be
