-----------------------------------
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.
