Subject [jira] [Commented] (CASSANDRA-4987) Support more queries when ALLOW FILTERING is used.
Date Mon, 08 Dec 2014 09:58:13 GMT


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.

> 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.
