How do I handle transient errors in my application?

Transient errors are temporary issues that can occur in applications, often due to network problems or service unavailability. A good approach is to implement retry logic with exponential backoff.

What is exponential backoff?

Exponential backoff is a strategy where you wait for a progressively longer time before each retry attempt. For example, you might wait 1 second, then 2 seconds, then 4 seconds, and so on.

Are there any libraries that can help with this?

Yes, many programming languages have libraries that support retry logic. For example, in Python, you can use the tenacity library, and in Java, you can use Resilience4j.

What should I log when a transient error occurs?

It's important to log the error message, the time it occurred, the number of retry attempts, and any relevant context that might help diagnose the issue later.
