             Summary: [Avatica] Support sessionless query requests
                 Key: CALCITE-668
                 URL: https://issues.apache.org/jira/browse/CALCITE-668
             Project: Calcite
          Issue Type: Improvement
            Reporter: Nick Dimiduk
            Assignee: Julian Hyde


Brought up over on CALCITE-663. One goal I have for Avatica is to support hosting a number of Avatica instances behind a "dumb" load balancer (i.e., round robin). This places the burden of implicit connection and statement creation on the protocol. A single client request should have everything it needs for a server to execute it, even if the server has never seen this client before.

There are different ways to accomplish this goal, some of which mentioned already include:
 - complete "session state" in all requests
 - multiple rpc methods passed in a single wire transaction
