What is the Retry Pattern?

The Retry Pattern is used in software development to handle transient faults or errors by automatically retrying failed operations. It provides a mechanism to retry an operation that has failed temporarily, with the hope that subsequent attempts will succeed. The Retry Pattern is commonly used in distributed systems, network communications, and interactions with external services where failures may occur due to temporary issues such as network congestion, timeouts, or resource unavailability.

• Retrying failed operations transparently without requiring user intervention helps maintain a seamless user experience.
• Users are less likely to encounter errors or disruptions, leading to increased satisfaction and engagement with the application.
• In scenarios where multiple components or services in a distributed system experience simultaneous failures, retries initiated by downstream services can lead to cascading retry storms.
• Managing retry storms and preventing amplification of failures require coordination and synchronization between components to avoid worsen the situation.

In software development, ensuring that applications remain resilient in the face of failures is crucial. Two key strategies that developers employ to enhance resilience are the Circuit Breaker and Retry patterns. These patterns offer solutions to handle failures gracefully and maintain system stability.
