What are common mistakes in retry implementations?

What are some common mistakes people make when implementing retry logic?

Some common mistakes include not considering idempotency, failing to implement exponential backoff, and not logging retries.

Can you explain why idempotency is important in retry logic?

Idempotency ensures that repeated requests have the same effect as a single request, preventing unintended side effects.

What is exponential backoff and why should I use it?

Exponential backoff is a strategy where the wait time increases exponentially with each retry, reducing server load and preventing congestion.

Are there any tools or libraries that can help with implementing retries?

Yes, many libraries like Polly for .NET or Resilience4j for Java provide built-in support for retry logic.
