Circuit breaker states
A circuit breaker trips to OPEN after repeated downstream failures. What does it do next before allowing traffic again?
Options
- 1It immediately retries all queued requests in a tight loop with no backoff and no probe limit at all
- 2It stays open permanently until an operator manually restarts the whole service to clear the state
- 3After a cooldown it moves to HALF-OPEN, allowing a few probe requests; success closes it, failure reopens it
- 4It switches all traffic to the fallback database until the downstream dependency recovers again
