Phoenix Client Backwards Compatibility
I'd like to build an application that talks to multiple Hbase clusters using Phoenix
I understand that those clusters might have different hbase versions and thus different phoenix-server versions
However ideally on our application side we only need to install one phoenix-client.jar
I was wondering if the phoenix-client is fully backwards compatible
i.e Can I use the latest phoenix-client to talk to all older versions phoenix-server?

A bit more context:
Older Phoenix clients are somewhat forward-compatible with newer servers,
but newer clients are definitely not backwards compatible with older
servers.
see https://phoenix.apache.org/upgrading.html
You also need to make sure that you do not try to use a client that
includes a newer HBase with an older HBase cluster.
With Phoenix Query Server, you can run a (or more) query server per
cluster, and use the same thin client to connect to each one.

It seems its perfect scenario for Phoenix Query service wh
<https://phoenix.apache.org/server.html>ere you don't have a thick client
which is dependent on the HBase version of the server side.
