(Radim: I'm assuming you mean do not delete already deleted columns as
Ross doesn't delete his rows.)
Just to be clear about Ross' situation: he continually inserts columns and
later deletes columns from the same set of rows. As long as he *doesn't* *keep
deleting already-deleted columns*
Has anyone seen this particular NPE before from Cassandra?
This is on 1.0.8. It seems to happen transiently on multiple nodes in my
cluster, every so often, and goes away.

Hi,
I have a column family that uses a composite key:

Ok, great. I'll be sure to look into the virtualization-specific NTP

Another benefit of using Cassandra over Zookeeper for locking is that you
don't have
performance than ZooKeeper for storing snapshots, especially as transaction
size increases

I'm using ZooKeeper to provide locking when I'm in need of some concurrency
