UniAPI's circuit breaker mechanism is an important guarantee of its high availability, using a hierarchical protection strategy:
- fault detection: The system continuously monitors the response status of each API service and triggers the protection mechanism when continuous failure is detected.
- hierarchical treatment::
- 3 failures: suspension of the service for 5 minutes
- 4 failures: 10-minute suspension
- 9 failures: 48-hour suspension
- automatic switching: During a pause, the system automatically routes requests to other available service providers
- Progressive recovery: After the cooling-off period, the system will attempt to restore the service
This mechanism is designed with that in mind:
- Avoid wasting resources and time with persistent requests for failed services
- Allow a window of recovery time for service providers
- Protection against short-term fluctuations and long-term failures through progressive pause times
- Ensure high availability of the overall service
Developers don't have to manually deal with service failures, the system is automatically kept running optimally, which is one of the key features that makes UniAPI suitable for enterprise-class applications.
