Quick update: diehard 0.2.2 released with circuit breaker support. ;; Define a circuit breaker with failure threshold: ;; it will be open when 35 executions in 50 failed ;; and it waits 1000ms to become half-open, and tests 50 executions to ;; see if failure is recovered
(diehard/defcircuitbreaker test-cb {:failure-threshold-ratio [35 50]
:delay-ms 1000})
;; you code within `with-circuit-breaker` will be protected by this
;; circuit breaker `test-cb`
;; if it's open, the block will throw a
;; `net.jodah.failsafe.CircuitBreakerOpenException`
;; and fail fast without blocking.
(diehard/with-circuit-breaker test-cb
;; your protected code here
)
