How can I effectively handle errors in event-driven systems?

In event-driven systems, it's crucial to implement robust error handling to ensure system reliability. You can use techniques like retries, dead-letter queues, and circuit breakers.

What are dead-letter queues and how do they work?

Dead-letter queues are used to store messages that cannot be processed successfully. They allow you to analyze and handle these messages later without losing them.

Can you explain the circuit breaker pattern?

The circuit breaker pattern prevents an application from repeatedly trying to execute an operation that's likely to fail. It temporarily blocks requests to a failing service, allowing it to recover.

What are some common pitfalls in error handling?

Common pitfalls include failing to log errors, not implementing retries, and neglecting to monitor error rates, which can lead to undetected issues.
