How does the Retry pattern work in microservices, and why is it important?

Short answer: The Retry pattern involves retrying an operation that has failed due to transient issues, such as network glitches, temporary unavailability of resources, or timeouts.

Explain a bit more

Why it’s important: It helps to recover from temporary failures that are often due to issues like network latency or service downtime. It enhances resilience and improves the user experience by reducing the impact of short-lived failures. Implementation:

Real-world example (ShopNest)

If Payment is down, the Order service fails fast with a circuit breaker instead of hanging every checkout thread.
