James Taylor commented on PHOENIX-971:
--------------------------------------
Great stuff, [~ndimiduk]. One question about the URL for the remote driver:
What's the typical JDBC way of differentiating a remote/thin driver from a
thick driver ([~julianhyde] may know)? You've used jdbc:phoenix:remote, but I'm
worried that this may not co-exist with our existing URL (in that if
PhoenixDriver is registered and on the classpath, it might use that one given
that URL, thinking that "remote" is the Zookeeper quorum). I seem to remember
something like jdbc:phoenix:// would mean it's remote. At least that's how our
existing Driver interprets that - see toward the end of
PhoenixEmbeddedDriver.acceptsURL(String url).
Second question (and maybe a dumb one), but do we need a dependency on jruby
for this, as I noticed that in the pom.
Third question: if there were a pool of query servers with a load balancer in
front of them, would everything just "work"? Is that the expected architecture?
One final question: is the client/server protocol stable, as once this gets
rolled out, changing that will be difficult. Is there a version number embedded
in the protocol? How does it help to maintain b/w compat?
Very exciting stuff.

> Host the JDBC driver in a query server process that can be deployed as a
> middle tier between lighter weight clients and Phoenix+HBase. This would
> serve a similar optional role in Phoenix deployments as the
> [HiveServer2|https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2]
> does in Hive deploys.
