Subject [jira] [Commented] (CASSANDRA-4987) Support more queries when ALLOW FILTERING is used.
Date Mon, 01 Dec 2014 15:49:13 GMT


Rajanarayanan Thottuvaikkatumana commented on CASSANDRA-4987:

[~ slebresne] In the Video table example of CASSANDRA-4915, if we issue a command {{SELECT
* FROM videos WHERE tags = 'Cassandra';}}, then it will give error {{code=2200 [Invalid query]
message="No secondary indexes on the restricted columns support the provided operators: "}}.
Is the idea to have {{ALLOW FILTERING}} option in the SELECT statements to support these kinds
of WHERE clauses and the like otherwise NOT supported by Cassandra now? Thanks

> 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.
