Circuit Breaker Pattern
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
When a service fails (e.g., response timeout) and the failure rate reaches a threshold, the system automatically cuts off calls to that service (trips the circuit), directly returning an error or fallback, giving the faulty service time to breathe and recover, preventing the entire system from collapsing.
SCAFFOLDING EFFECT
Reduce cognitive load
Stop-loss and self-healing. In investment or personal energy management, a 'circuit breaker' must be set. For example: force liquidation when losses reach 20%; force rest after 3 consecutive days of overtime. Prevent local failures from dragging down the whole.
Anchor fast decisions
A distributed system design pattern where calls to a remote service 'trip' and fail fast when consecutive failures reach a threshold, avoiding thread/resource exhaustion from slow calls, and giving the dependency time to recover before half-open probing.
