Josh Elser commented on CALCITE-767:
------------------------------------
Did some prelim testing of this using Phoenix and protobuf. Using Phoenix's
pherf tool, I was able to run the same test against the normal Phoenix driver
and the Avatica-based Phoenix thin driver. For those curious, performance
degredation without any thought of optimization in Avatica: 5x. Pretty good for
a first pass, IMO.
I'm going to rebase/merge this in tonight.

>
> It seems that the commit/rollback functionality is not exposed by the RPC
> server, which means that it's only usable in autocommit mode. Avatica itself
> doesn't have a concept of commit in the RPC and the remote JDBC connection
> raises an exception when calling commit() on it, but Phoenix's native JDBC
> connection does implement commit(), so the RPC needs to be extended to allow
> calling that remotely.
> The easiest way to test this, "!autocommit off" and then "!commit" fails in
> "sqline-thin.py", but works in "sqline.py".
