larzretry
Resilience for flaky operations — retry with backoff, and a circuit breaker.
Real apps call things that fail intermittently: networks blip, services hiccup, databases briefly stall. larzretry makes those operations resilient — retry a failing call a few times (with optional exponential backoff), or wrap a troublesome dependency in a circuit breaker that stops hammering it once it's clearly down. Sleep and clock are injectable, so it's fully testable. Zero dependencies.
Install
pip install larzretry
Use
from larzretry import retry, call, CircuitBreaker
@retry(times=3, backoff=0.1)
def fetch():
return risky_network_call()
call(fetch, times=5, exceptions=(ConnectionError,))
breaker = CircuitBreaker(threshold=3, reset_after=30)
breaker.call(fetch) # fails fast once the dependency is clearly down
