If the external GIS geocoder is down, the address-lookup feature should fail fast after repeated errors and serve a degraded enter-manually path instead of hanging every request. Which pattern is this?
Select an answer to reveal the explanation.
Short Explanation
After enough sparks, flip the breaker so you stop shoving current into a dead geocoder. Fail fast, offer the manual address path, then peek with a half-open trial later. That circuit-breaker pattern keeps the rest of the portal healthy.
Full Explanation
Circuit breakers trip open after repeated failures, fail fast without calling the unhealthy dependency, optionally serve degraded behavior, and periodically half-open to test recovery. Unlimited retries and max timeouts keep threads hung. Crashing the process spreads the outage. This pattern is part of resilient third-party integration skills on DVA-C02.
