Feature Proposal: Distributed Circuit Breaker Support

[call-stack]

Hi maintainers,

I'd like to propose adding distributed circuit breaker support to Sony/gobreaker by allowing the circuit breaker state (open/closed/half-open) to be stored in an external datastore like Redis. This would allow multiple service instances to share the same state, ensuring consistent behavior across all instances.

Key Proposal:

• Optional External State: Allow users to opt-in to store circuit breaker state in a shared store (e.g., Redis) for distributed environments.
• Backward Compatibility: In-memory state management remains the default.
• Pluggable Interface: Introduce a pluggable interface for different datastores (Redis, etc.).

Benefits:

• Consistent circuit breaker state across multiple instances.
• Prevents downstream overloads in distributed systems.

I’d be happy to contribute a PR for this feature if it aligns with the project’s goals. Let me know your thoughts!
