Source: content/manual/06-glossary/architecture/circuit-breaker.md
Definition
Pattern that stops calls to a failing dependency to prevent cascading failures, then probes for recovery.
Why it matters
Improves system stability and reduces MTTR by isolating faults.
Common pitfalls
- Poorly tuned thresholds causing flapping.
- No fallback behavior or user messaging.
