Authlete replaces Cloud SQL with YugabyteDB and achieves zero downtime during rolling maintenance by changing a few settings and small client-side tweaks. Compatibility testing passes after setting one configuration flag, JDBC behavior improves with the Yugabyte smart JDBC driver and a reduced node-list refresh interval, and minor retry logic in the DB layer prevents lost-connection errors. Full rolling DB maintenance runs without HTTP errors; pilot deployments show comparable or better latency and enable future dual-region and active‑active options.
