Retry with Exponential Backoff

Retry transient failures with progressively longer waits and jitter.

retry

Detailed Description

Retries are only safe when the operation is idempotent or protected by idempotency keys.

Always add jitter so many clients do not retry at the exact same time.

fail -> wait 100ms
fail -> wait 200ms
fail -> wait 400ms + jitter
success or give up

Pros

Handles transient failures

Cons

Increases latency, requires idempotency

Examples: axios-retry, got retry, AWS SDK retry
