Sylvain Lebresne commented on CASSANDRA-4987:
---------------------------------------------

No, the changes are not trivial and the complexity of doing it on top of the 
current engine doesn't clearly balance the benefit. Which is why I think the 
proper way to fix this is just to wait for CASSANDRA-8099 that should handle 
that cleanly right off the bat. So I'm going to close this as duplicate of 
CASSANDRA-8099 for now. If the latter doesn't pan out of any reason, we can 
reconsider this separatly but let's hope we won't need to.

> Support more queries when ALLOW FILTERING is used.

> Even after CASSANDRA-4915, there is still a bunch of queries that we don't 
> support even if {{ALLOW FILTERING}} is used. Typically, pretty much any 
> queries with restriction on a non-primary-key column unless we have one of 
> those restriction that is an EQ on an indexed column.
> If {{ALLOW FILTERING}} is used, we could allow those queries out of 
> convenience.
