Jonathan Ellis commented on CASSANDRA-2474:
-------------------------------------------
I don't think anything we do here is going to be 100% intuitive with respect to
the sorting behavior (I can't think of a way to make a SQL database sort by
columns X and Y, but only within the same column Z, which is itself ordered
randomly), so I'd rather avoid inventing non-SQL syntax. And the PRIMARY KEY
syntax is still a good fit for the "you can't update the PK directly" behavior.

> For the most part, this boils down to supporting the specification of
> compound column names (the CQL syntax is colon-delimted terms), and then
> teaching the decoders (drivers) to create structures from the results.
