------------------------------------------------------------------------
poc.patch adds an optional 'keyspace' argument to the QUERY message. I have
verified that it behaves properly in my environment with a modified version of
the Ruby driver, but the intent is really to get an initial code review and
address questions/concerns I discuss in comments / text annotated with
"sandman:". The two main concerns are:
1. What to do with PREPARE messages since they don't currently have a flags
byte for optional arguments.
2. Should 0x80 in flags be defined to say "there is another byte of
extra-flags; look there for additional optional parameters to this message".
You need not bother running this code; this patch is a partial implementation
of this feature and is meant as a proof of concept. Based on feedback and
discussion, I'll flesh it out, add tests, etc., and then submit a new patch.

> Change protocol to allow sending key space independent of query string

> Project: Cassandra
> Issue Type: Improvement
> Reporter: Vishy Kasar

> Attachments: poc.patch

>
> Currently keyspace is either embedded in the query string or set through "use
> keyspace" on a connection by client driver.
> There are practical use cases where client user has query and keyspace
> independently. In order for that scenario to work, they will have to create
> one client session per keyspace or have to resort to some string replace
> hackery.
> It will be nice if protocol allowed sending keyspace separately from the
> query.
