Implementing Circuit Breaker Pattern in Go for Fault Tolerance
In today’s distributed systems landscape, services are interconnected through complex networks of API calls, database queries, and external service dependencies. When one service experiences issues, it can create a cascading failure that brings down entire systems. This is where the Circuit Breaker pattern becomes invaluable—acting as a protective mechanism that prevents failing services from overwhelming the entire system.
The Circuit Breaker pattern, inspired by electrical circuit breakers, monitors service calls and “trips” when failures exceed a certain threshold, temporarily blocking requests to give the failing service time to recover.
