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
