Retry Logic
Retry logic is a programming pattern that automatically re-attempts failed operations, such as network requests or database queries, to handle transient errors and improve system resilience. It involves implementing mechanisms to catch exceptions, wait before retrying, and limit the number of attempts to prevent infinite loops. This concept is widely used in distributed systems, microservices, and cloud applications to manage unreliable network conditions and temporary service outages.
Developers should learn and use retry logic when building applications that depend on external services, APIs, or network resources prone to intermittent failures, such as in microservices architectures or cloud environments. It is essential for ensuring fault tolerance and reliability, as it helps recover from transient errors like timeouts, rate limits, or temporary unavailability without requiring manual intervention. Specific use cases include handling HTTP requests in web applications, database connections, and message queue processing.
