Closed

The circuit breaker is not open and all requests are

executed.

▪ Open

The Circuit Breaker is open and it prevents the

application from repeatedly trying to execute an

operation while an error occurs.

▪ Half-Open

The Circuit Breaker executes a few operations to

identify if an error still occurs. If errors occur, then the

circuit breaker will be opened, if not it will be closed.
