Implementing fault tolerance patterns to prevent cascading system failures.
In a distributed system, failure is inevitable. The Circuit Breaker pattern is the primary defense against cascading failures. We examine the 'Open', 'Closed', and 'Half-Open' states of a circuit and how to implement them in high-concurrency environments.
We also compare libraries like Resilience4j and Hystrix, providing a Go implementation for a custom interceptor-based circuit breaker.
