How can I handle errors in a publish-subscribe system?

In a publish-subscribe system, you can handle errors by implementing retry mechanisms, logging errors, and using dead-letter queues.

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 reprocess these messages later.

Can you give me an example of a retry mechanism?

Sure! A common retry mechanism is exponential backoff, where the wait time between retries increases exponentially.

What tools can I use to implement these error handling strategies?

You can use message brokers like RabbitMQ or Apache Kafka, which have built-in support for error handling and retries.
