select compositetype keys in cassandra
===

So I've defined a column family that uses composite ids for the row keys. So say the composite key is `CompositeType(LongType,LongType)`. So I've tested storing items with this type and that works fine and `SELECT` works as expected too when I know the full key. But lets say I want all keys that have 0 as the first element and anything as the second. So far the only way that I can see to perform this query is as follows:

if I was all keys that are 0:* then I would do a CQL query for `key >= 0:0 AND key < 1:0` which works as long as there is an order preserving partitioner.

My questions are:

1) is this odd syntax only because I'm using a CQL driver (only option for nodejs aside from thrift)

2) is there any inefficiency with this type of query? essentially i'm using a composite key instead of super columns since those aren't supported in CQL. I have no problem dealing with this logic in the code as long as there is no limitations to using it like this.
