Design Microservices Architecture with Patterns and Principles - Circuit Breaker States

The video tutorial explains the three basic modes of a circuit breaker: closed, open, and half-open. In the closed state, all requests are executed as the circuit breaker is not open. The open state prevents the application from executing operations when errors occur, acting as a response to previous failures. The half-open state allows a few operations to check if errors persist, determining whether to open or close the circuit breaker.

Explain the half open state of a circuit breaker.

What determines whether the circuit breaker will be opened or closed in the half open state?
