Cristian Manuel Vertiz Fernandez commented on CASSANDRA-3069:
-------------------------------------------------------------

I know that UNION won't be efficient but what if I need to query something like this (you
know sometimes it's necessary):

SELECT * FROM columnFamily where id = 24398 LIMIT 1
UNION
SELECT * FROM columnFamily where id = 24399 LIMIT 1
UNION
SELECT * FROM columnFamily where id = 24399 LIMIT 1

columnFamily
 id            | time                                                                    
 | value                                      
    24398 | 2015-04-24 10:41:26SA Western Standard Time |
