Overview ¶
Package circuitbreaker implements the circuit breaker pattern.
Circuit breakers prevent thundering herds, and improve resiliency against intermittent errors. Every client-side endpoint should be wrapped in a circuit breaker.
We provide several implementations in this package, but if you're looking for guidance, Gobreaker is probably the best place to start. It has a simple and intuitive API, and is well-tested.
