Eric Evans commented on CASSANDRA-3424:
---------------------------------------
OK, so stepping a back a bit...
If we have semantics which are stable and expected in some version, and we
alter those in a future version (for anything other than a major version
change), that is a regression. So even if this patch had done what it intended
to do, it would be a regression, and we have always fixed regressions as
quickly as possible.
While it would make it no less of a regression, if this change had resulted in
SQL semantics, it could be considered an improvement, but that is not the case.
The pre-3424 behavior at least benefits from being consistent with how the RPC
interface works, and every prior CQL-enabled version of Cassandra.
So I believe we should revert this change because:
# It signals that we are serious about maintaining the contract we've made with
our users
# The original behavior (while not ideal) better satisfies the element of
least-surprise
> Selecting just the row_key returns nil instead of just the row_key
