go-idempotent-retry-patterns

What problem does it solve?

This Skill provides robust retry mechanisms for Go SDK operations to ensure resilience against transient errors and network issues.

Core Features & Use Cases

• Error Retry Predicate: Implements a function to determine if an error is retryable based on sentinel comparisons and error types.
• Context-Aware Backoff: Provides a pattern for exponential backoff with jitter that respects context cancellation, preventing goroutine leaks.
• Idempotency Support: Includes guidance on using message IDs for server-side deduplication with JetStream and header-based idempotency for HTTP.
• Use Case: Ensuring message publishing retries do not cause duplicate data insertion in high-reliability systems.

Quick Start

Integrate the provided IsRetryable predicate and executeWithRetry function into your Go application to handle transient errors gracefully during message publishing.
