Polly v8 Strategies in Depth: Retry, Timeout, Circuit Breaker, Rate Limiter and Fallback
In Polly v8 the order of strategies decides behavior: total timeout outside, retry in the middle, attempt timeout inside; MaxDelay doesn't cap Retry-After, and a timeout can't stop code that ignores the token. In Bookstore we build, with real output, a named pipeline for SMTP, a retry that honors Retry-After, a circuit breaker with manual control and a health check, a concurrency limiter, and a flat-tariff fallback for carrier prices.
