Nick Dimiduk commented on PHOENIX-971:
--------------------------------------
Hi [~sergey.b], yes, that's exactly right. The only client implantation Avatica
has at the moment is a Java client, but the protocol currently is just
HTTP/JSON and we intend to add other clients. The RPC API has been evolving
rapidly since Calcite 1.0, so there's not yet been an attempt to document it
properly. As we push avatica toward feature completeness, the surface area will
solidify and documentation will be more of a pressing concern. We'd be happy to
accept help building out support for the environments you find important.

> 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.
