The Circuit Breaker is a design pattern commonly used in software development to improve system resilience and fault tolerance.
[1] In distributed systems, the Circuit Breaker pattern can be used to monitor service health and can detect failures dynamically.
Unlike timeout-based methods, which can lead to delayed error responses or the premature failure of healthy requests, the Circuit Breaker pattern can proactively identify unresponsive services and can prevent repeated attempts.
If the number of failures increases beyond the threshold, the circuit breaker trips and goes into an open state.
In this state, the circuit breaker allows a limited number of requests from the service to pass through and invoke the operation.
