Sylvain Lebresne commented on CASSANDRA-5443:
---------------------------------------------
bq. ATOMICALLY is redundant with the IF, isn't it?
It is, strictly speaking. But adding it nails down the fact that this is a
relatively specific operation, which fairly different performance
characteristics, and one that returns a value. Also, I figured we may use
something like "atomic updates" to describe them in the docs/presentations and
so having atomic in the syntax would avoid having to add every time "that's the
ones with a IF". Overall, I have the feeling that having a clearer syntactic
differentiation is probably good.
bq. I do have a stronger preference for IF being the last clause.
I'm perfectly fine with that.
