Hi, I've been playing around with CAS (compare-and-swap) in the 2.0 beta, using the Thrift API. I can't at all figure out how to delete columns while using CAS, however. I'm able to update/insert columns by adding them to the list of updates that is passed as a parameter to org.apache.cassandra.thrift.Cassandra.Client#cas(). But there seems to be no indication as to how to delete.
I presume it can be done because conditional deletes work through CQL3. However, I'm interested in using Hector/Java (particularly as CQL3 does not yet allow batched conditional statements). Any help would be great! Thanks, Kalpana
