on YouTube ↗42m

" summary

Polly is an OSS resilience library on GitHub that runs on .NET 4.5+ and .NET Core 2.1 and integrates with HttpClientFactory; it implements retry, wait-and-retry with exponential back-off, circuit breaker breaks after 4 failures for 3s, bulkhead isolation preserved good endpoint. A local demo server throttles after 3 calls per 5s; 20 retries succeed where simple retries fail; circuit breaker prevents cascading retries; bulkheads keep one endpoint responsive (28 succeeded) while the faulting endpoint fails. Downloads exceed 16 million across 47 releases.
