Retries with Backoff

Description

The Retry pattern enables an application to handle transient failures when it tries to connect to a service or network resource, by transparently retrying a failed operation. Exponential backoff increases the wait time between retries to avoid overwhelming the system.

Where to use

  • Connecting to remote services.
  • \n
  • Handling temporary network glitches.
  • \n
  • Database connections.

Real World Example

Calling an external Weather API. If it returns 503, wait 1s and retry. If fail, wait 2s, then 4s, then give up.
