gruf-circuit-breaker - Circuit Breaker for gruf

Adds circuit breaker support for gruf 2.0.0 or later.

This uses the wonderful stoplight gem for handling the internals of circuit breaking.

gem 'gruf-circuit-breaker'

Then in an initializer or before use, after loading gruf:

require 'gruf/circuit_breaker'
Gruf::Hooks::Registry.add(:circuit_breaker, Gruf::CircuitBreaker::Hook)

You can further customize the tracing of gruf services via the configuration:

Gruf.configure do |c|
  c.interceptors.use(Gruf::CircuitBreaker::Interceptor, { 
    # set cool-off time in seconds (defaults to 60)
    cool_off_time: 15, 
    # set threshold count to 2
    threshold: 2, 
    # set the gRPC failure statuses that will cause a circuit to trip 
    failure_statuses: [GRPC::Internal, GRPC::Unknown, GRPC::Aborted],
    # use a redis instance for the stoplight data storage
    redis: Redis.new
  })
end
