-------------------------------------------

What I want to avoid is a special query type (i.e. anything not "SELECT")
because it makes the language less orthogonal because of implementation details
that are subject to change (in an ideal world, we'd move away from avro and
store schema information in "real" columns, with indexes so you could easily
say "give me all the columns for CF X at schema version Y.")
You'd also be limited to basically an RPC style call – no specifying which
columns to select, or which rows you're interested in. Not without reinventing
that wheel on a LOT of code (because SELECT right now relies on CFS to perform
the actual queries).
