Abe Ratnofsky updated CASSANDRA-17704:
--------------------------------------
Resolution: (was: Not A Problem)
Status: Open (was: Resolved)
This behavior is feasible - I've put together a branch with passing unit tests:
[https://github.com/apache/cassandra/compare/trunk...aratno:cassandra:CASSANDRA-17704-order-by-after-in-clustering]
Would someone be able to re-open this one and comment here on the questions
posed in StatementRestrictions.clusteringKeyPrefixIsIn?
> Cannot specify ORDER BY of clustering columns after IN-clause constraints on

> Key: CASSANDRA-17704
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17704
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Semantics
> Reporter: Abe Ratnofsky
> Assignee: Abe Ratnofsky
> Priority: Normal
>
> When a user specifies a partition key and clustering key prefix with equality
> predicates, C* supports sorting by the next clustering key (CASSANDRA-10271):
> {code:java}
> SELECT * FROM tbl WHERE pk = 1 AND ck1 = 1 ORDER BY ck2;{code}
>
> When a user specifies a partition key with a set-membership predicate, C*
> supports sorting by the next clustering key (requires merge sort of results
> for each pk):
> {code:java}
> SELECT * FROM tbl WHERE pk IN (1, 2) ORDER BY ck1;{code}
>
> But when a user specifies a partition key with an equality predicate and a
> clustering key prefix with a set membership predicate, C* *does not* support
> sorting by the next clustering key:
> {code:java}
> SELECT * FROM tbl WHERE pk = 1 AND ck1 IN (1, 2) ORDER BY ck2;
> org.apache.cassandra.exceptions.InvalidRequestException: Order by currently
> only supports the ordering of columns following their declared order in the
> PRIMARY KEY
> {code}
>
> This last situation requires a merge sort, but so does the multi-pk situation.
>
> The docs seem to indicate that this pattern is supported, as well:
