The circuit breaker pattern prevents calls to be made to a failing resource once the number of failures cross a particular threshold. To implement the circuit breaker pattern, wrap calls made to a service in a circuit breaker object. The circuit breaker monitors the failures attempts made to the service. Once the number of failed attempts to invoke a service exceeds a threshold value, the circuit trips for that service and any further calls to the service are short-circuited. The circuit breaker may keep the count of failed requests made to the service in a shared cache so that the count may be shared across all instances of the application. This setup ensures that application does not waste resources in waiting for response from a failing service. A fallback logic maybe implemented that gets invoked when the circuit breaker trips while the connection is still open which may return a value to the client application:
