circuitbreaker
A Go library implementing the Circuit Breaker pattern to handle remote call failures and prevent resource exhaustion.
What is circuitbreaker?
circuitbreaker is a Go library that implements the Circuit Breaker pattern to protect applications making remote calls. It prevents resource exhaustion when remote calls hang or fail by tripping after defined failures and temporarily blocking further calls. The library provides multiple breaker types, timeout wrapping, and an HTTP client wrapper for building fault-tolerant distributed systems.
Go developers building distributed systems or microservices that make remote calls to external services, APIs, or databases. It is particularly useful for engineers needing to prevent cascading failures and manage fault tolerance in high-volume applications.
Developers choose circuitbreaker for its simplicity, reliability, and comprehensive feature set including multiple breaker strategies (threshold, consecutive, rate), manual control, and built-in HTTP client support. It follows established patterns from Martin Fowler and Netflix, making it a trusted solution for implementing circuit breaking in Go applications.
