How do I handle transient failures in my application?

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

What is exponential backoff?

Exponential backoff is a strategy where the wait time between retries increases exponentially. For example, if the first retry waits 1 second, the next might wait 2 seconds, then 4 seconds, and so on.

Are there any libraries that can help with this?

Yes, many programming languages have libraries for handling retries. For example, in Python, you can use the tenacity library, and in Java, you might use Resilience4j.

What should I log when a transient failure occurs?

It's important to log the error message, the time of the failure, the number of retries attempted, and any relevant context that can help diagnose the issue later.
