Circuit Breaker Pattern: Fail Fast, Not Hard
Source: Wikipedia: Circuit breaker patternadvanced
A circuit breaker wraps network calls to prevent cascading failures. It monitors for errors, and if a service seems down, it 'trips' to fail requests instantly without hitting the network. This gives the failing service time to recover.
Think of it like an electrical breaker for API calls. It wraps requests to a service, and if enough failures occur, it 'trips' open, failing calls immediately. This prevents your app from hammering a dead service. The main footgun is misconfiguring thresholds, causing it to trip too easily for transient blips or not at all during a real outage.
