Circuit Breakers

A circuit breaker temporarily stops calls to an unhealthy dependency so the wider system can recover or use a fallback.

WHY IT MATTERS

Continuing to hammer a failing model provider or tool wastes capacity and extends latency.

PRODUCTION EXAMPLE

After repeated provider timeouts, the circuit opens for 30 seconds and eligible traffic uses a fallback model.

SRE DECISION

What health signal opens and closes the circuit?

REMEMBERCircuit breakers prevent one sick dependency from infecting the entire request path.
