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.

Code Example

# Code Concept for Retries with Backoff
# This pattern is architectural.

class Service:
    def execute(self):
        # Implementation logic
        pass
