If you are using OPP, then you can use CompositeType on both key and
column name; otherwise(Random Partition), just use it for columns.

With the current implementation of CompositeType in Cassandra 0.8.1,
is it recommended practice to try to use a CompositeType as the key?
Or are both, column and key, equally well supported?
The documentation on CompositeType is light, well non-existent really, with
key_validation_class set to CompositeType (UUIDType, IntegerType)
can we query all matching rows just by using CompositeType(UUIDType)?
In my specific use case, what would work best is to have a composite
key that is a CompositeType with thousands of columns each.
