Polly

Overview

Polly is a .NET resilience and transient-fault-handling library that offers developers the ability to implement resilience strategies such as Retry, Circuit Breaker, Hedging, Timeout, Rate Limiter, and Fallback in a fluent and thread-safe manner. The library is a member of the .NET Foundation and provides users with various strategies to enhance the fault-tolerance and reliability of their applications.

Features

• Retry: Automatically retries operations in case of transient faults.
• Circuit Breaker: Breaks the circuit to prevent overloading a struggling system.
• Hedging: Deals with high-latency or at-risk operations by issuing parallel requests.
• Timeout: Ensures operations complete within a specified timeframe.
• Rate Limiter: Controls the rate at which operations are executed.
• Fallback: Provides a fallback mechanism in case of failures.

Summary

Polly is a versatile .NET resilience library that empowers developers to implement various resilience strategies in their applications. With features like Retry, Circuit Breaker, Hedging, Timeout, Rate Limiter, and Fallback, Polly provides a robust framework for handling transient faults and enhancing application reliability. Whether through automatic retries, circuit-breaking mechanisms, or rate limiting, Polly offers a comprehensive set of tools to improve fault-tolerance and ensure smooth operation of .NET applications.
