             Summary: Better control over retried operations in Avatica client
                 Key: CALCITE-1316
                 URL: https://issues.apache.org/jira/browse/CALCITE-1316
             Project: Calcite
          Issue Type: Improvement
          Components: avatica
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: avatica-1.9.0


We have at least two places in the Avatica client now where we will try to re-issue "RPCs" in the attempt to work seamlessly with load-balanced servers.

Between these two places, we have finite retries, infinite retries and no standardized back-off strategies. We should try to centralize this into one place and make sure that users can override the logic, heaven forbid they come up with some situation where it's necessary.

Need to investigate the retry-loops we have in the Avatica client now, categorize the loops and come up with a minimal set of knobs to configure the retries, expose those knobs in the JDBC URL string options, and update the documentation.
