>                 Key: CASSANDRA-4327
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4327
>             Project: Cassandra
>          Issue Type: Improvement
>    Affects Versions: 1.1.1
>            Reporter: Stephen Powis
>            Assignee: Pavel Yaskevich
>            Priority: Minor
>              Labels: cql3
>             Fix For: 1.1.3
>
>         Attachments: CASSANDRA-4327.patch, CASSANDRA-4327-v2.patch, trunk-4327.txt

> Using the following test schema:
> CREATE TABLE test (
>   my_id varchar, 
>   time_id uuid,
>   value int,
>   PRIMARY KEY (my_id, time_id)
> );
> When you issue a CQL3 query like: 
> select * from test where my_id in('key1', 'key2') order by time_id; 
> You receive the error:
> "Ordering is only supported if the first part of the PRIMARY KEY is restricted by an Equal"
> I'm including a patch I put together after spending an hour or two poking thru the code base that sorts the results for these types of queries.  I'm hoping someone with a deeper understanding of Cassandra's code base can take a look at it, clean it up or use it as a starting place, and include it in an upcoming release.
