How can I implement error handling in an event bus system?

Implementing error handling in an event bus involves several strategies, such as using try-catch blocks, logging errors, and implementing retry mechanisms.

What are some common errors I should be aware of?

Common errors include message serialization issues, network failures, and event processing timeouts.

How can I log errors effectively?

You can use structured logging to capture error details, including timestamps, event IDs, and stack traces for easier debugging.
