Circuit Breaker Pattern
A core microservices architectural design pattern described by Martin Fowler in 2014, used to prevent cascading failures. The circuit breaker operates in three states—closed, open, and half-open—and in agent tool-calling scenarios can conserve LLM token budgets while protecting downstream services.
Timeline (last 90 days)
The circuit breaker pattern has three states: closed (requests pass through), open (requests are rejected and fail fast), and half-open (a small number of probe requests are allowed to detect recovery); it opens when consecutive failures exceed a threshold and enters half-open after a cooldown.
OmniRoute's failover design shares the same lineage as the circuit breaker pattern concept in traditional microservices.
Industry best practices include setting a maximum number of retries, distinguishing between retryable errors (such as 429 rate limiting) and non-retryable errors (such as 400 parameter errors), and combining the Circuit Breaker pattern to completely block calls to faulty services.
The circuit breaker pattern was popularized at scale by Netflix, automatically breaking the circuit when the downstream error rate exceeds a threshold and rejecting subsequent requests rather than continuously retrying.
A complete circuit breaker contains three states: Closed (normal pass-through), Open (requests rejected directly), and Half-Open (a small number of probe requests are allowed to detect whether the service has recovered).
