golang-resilience

What problem does it solve?

It helps developers implement reliable network communication by applying resilience strategies in Go services.

Core Features & Use Cases

• Circuit Breaker Implementation: Prevents cascading failures by controlling external service calls. For example, stopping repeated calls to a failing API.
• Timeout Management: Ensures each network boundary has appropriate deadlines, avoiding hangs and resource exhaustion. For instance, setting specific timeouts for database or API calls.
• Retry Mechanisms: Implements exponential backoff with jitter to handle transient errors efficiently, reducing call failures and improving stability.
• Bulkhead Isolation: Limits concurrent requests to dependencies, preventing resource starvation. For example, capping concurrent database queries.
• Hedged Requests: Sends simultaneous requests to multiple replicas to reduce latency and improve response time in critical paths.
• Fallback Strategies: Provides fallback responses or cached data when dependencies fail, ensuring service continuity.

Quick Start

Use the resilience patterns to improve the fault tolerance of your Go microservices by configuring timeouts, circuit breakers, retries, bulkheads, hedges, and fallbacks.
