---------------------------------------------------------------
re: KS/CF metadata. As you say, JDBC/SQL can have resultset information from
many tables, which is why you can acquire that metadata information at the
column level. The {{ResultSetMetaData}} interface provides methods for
{{getSchemaName(column)}} and {{getTableName(column)}} on a column-by-column
basis. The point is tools use these interfaces and methods heavily to deliver
their functionality and we will improve adoption of the Server and the Driver
if we can make the interface process for these tools deliver as much
information as practical.

> A custom wire protocol would give us the flexibility to optimize for our
> specific use-cases, and eliminate a troublesome dependency (I'm referring to
> Thrift, but none of the others would be significantly better). Additionally,
> RPC is bad fit here, and we'd do better to move in the direction of something
> that natively supports streaming.
> I don't think this is as daunting as it might seem initially. Utilizing an
> existing server framework like Netty, combined with some copy-and-paste of
> bits from other FLOSS projects would probably get us 80% of the way there.
