Açıklaması şöyle

- registerHealthIndicator: true: This line is telling the service to register a health indicator, which can be used to monitor the overall health of the service.

- eventConsumerBufferSize: 10: This is the size of the buffer that will store events from the Circuit Breaker.

- failureRateThreshold: 10: This is the threshold for the failure rate of calls. If the failure rate of calls exceeds this threshold, the Circuit Breaker will trip.

- minimumNumberOfCalls: 5: This is the minimum number of calls that the Circuit Breaker will monitor before it starts tripping.

- automaticTransitionFromOpenToHalfOpenEnabled: true: This line enables automatic transition from the open state to the half-open state after the wait duration has elapsed.

- waitDurationInOpenState: 5s: This is the duration that the Circuit Breaker will wait in the open state before attempting to automatically transition to the half-open state.

- permittedNumberOfCallsInHalfOpenState: 3: This is the maximum number of calls that the Circuit Breaker will allow in the half-open state.

- slidingWindowSize: 10: This is the size of the sliding window that the Circuit Breaker will use to monitor calls.

- slidingWindowType: COUNT_BASED: This line specifies the type of sliding window that the Circuit Breaker will use, which in this case is a count-based sliding window. There are other options for slidingWindowType like TIME_BASED, TIME_BASED_RESET etc which can be used for specific use cases.
