Sylvain Lebresne commented on CASSANDRA-5633:
---------------------------------------------
I'm also quite reluctant in adding some sub-query syntax "just for this",
mainly for the cons expresses above, that is 1) the fact that it confuses quite
a bit the "we don't do sub-query" message and 2) it doesn't make it very clear
what the restrictions on that sub-query are. Which is not to say that I have a
much better idea. But maybe a better understanding of what this could be useful
for in practice could help here? Granted "thrift can do it" is one type of
argument, but outside that, a concrete CQL3 example of why this could be useful
could help might help making some progress?
