Timeout pattern

[iluwatar]

Description:
The Timeout design pattern is crucial in a microservices architecture to handle latency and prevent cascading failures. By setting a timeout, we can avoid long waits for responses from dependent services, improving overall system resilience and performance. This pattern helps in defining a period within which a service call must complete, otherwise, it gets aborted and a fallback mechanism is triggered. This implementation is particularly important for maintaining the robustness of the system under heavy load or when some services are down or slow to respond.

Main Elements of the Pattern:

• Timeout Duration: Defines the maximum time a service call is allowed to take.
• Fallback Mechanism: Provides a default response or alternative workflow if a service call times out.
• Configuration: Ability to configure different timeouts for different services based on their response times.
• Logging and Monitoring: Capture timeout events for monitoring and debugging purposes.
• Circuit Breaker Integration: Work in conjunction with the Circuit Breaker pattern to prevent repeated calls to failing services.

Acceptance Criteria:

• Implement a configurable timeout for service calls.
• Provide a fallback mechanism for timed-out calls.
• Ensure the timeout duration can be configured per service.
• Log timeout events for further analysis and monitoring.
• Demonstrate the pattern with a practical example within the existing microservices.
• Ensure the implementation follows the project's contribution guidelines and coding standards.
