Sylvain Lebresne updated CASSANDRA-5786:
----------------------------------------
Attachment: 5786.txt
Disregard the comment above. For normal updates we keep columns unsorted until
they are applied to the memtable and we should probably do that here too for
consistency. So attaching patch that makes sure we don't assume the columns are
sorted when deserializing for paxos.
> Thrift cas() method crashes if input columns are not sorted.
