-----------------------------------------
Resolution: Duplicate
As for CASSANDRA-6137, pretty sure this has been solved in CASSANDRA-6327.

> I have the following table:
> CREATE TABLE rating (
> id bigint,
> mid int,
> hid int,
> r double,
> PRIMARY KEY ((id, mid), hid));
> And I get really really strange result sets on the following queries:
> cqlsh:bm> SELECT hid, r FROM rating WHERE id = 755349113 and mid = 201310
> and hid = 201329320;
> hid | r
> -----------+--------
> 201329320 | 45.476
> (1 rows)
> cqlsh:bm> SELECT hid, r FROM rating WHERE id = 755349113 and mid = 201310
> and hid = 201329220;
> hid | r
> -----------+-------
> 201329220 | 53.62
> (1 rows)
> cqlsh:bm> SELECT hid, r FROM rating WHERE id = 755349113 and mid = 201310
> and hid in (201329320, 201329220);
> hid | r
> -----------+--------
> 201329320 | 45.476
> (1 rows) <-- WRONG - should be two records
> As you can see although both records exist I'm not able the fetch all of them
> using in clause. By now I have to cycle my requests which are about 30 and I
> find it highly inefficient given that I query physically the same row.
> More of that - it doesn't happen all the time! For different id values
> sometimes I get the correct dataset.
> Ideally I'd like the following select to work:
> SELECT hid, r FROM rating WHERE id = 755349113 and mid in ? and hid in ?;
> Which doesn't work either.
