Distributed applications may fail. Be prepared with MicroProfile Fault Tolerance
summary
MicroProfile Fault Tolerance version in MicroProfile 6.0 exposes annotations that run as CDI interceptors and the demo shows them working: timeout and fallback (example switches a DuckDuckGo call to Google when a sleep exceeds timeout), retry=3 (method auto-retries up to three times with configurable jitter and delays), and circuit opens at high failure rate (30% failures under load trigger open/half-open/closed behavior). Examples run on WildFly, use ApacheBench for concurrency, and full code and slides are on GitHub.
