fuse
A robust circuit breaker library for Erlang applications to prevent cascading failures and improve system resilience.
What is fuse?
Fuse is an Erlang/OTP application that implements the circuit breaker pattern, a fault-tolerance mechanism for distributed systems. It prevents cascading failures by detecting errors in dependent services and temporarily blocking requests, allowing systems to degrade gracefully and auto-heal when issues are resolved.
Erlang/Elixir developers building distributed systems with long dependency chains, such as microservices or layered applications, where service failures could cascade and cause latency or resource waste.
Developers choose Fuse for its correctness and reliability, backed by extensive property-based testing with Erlang QuickCheck to eliminate subtle concurrency and timing errors. It offers high performance with sub-microsecond overhead, configurable fuse types, and integration with monitoring systems like Prometheus.
