It implements the circuit breaker design pattern, which maintains system stability by preventing repeated calls to failing services during outages or maintenance windows. The library supports both synchronous and asynchronous code paths and can be used as a context manager or decorator, making it flexible for different integration patterns.\n\nThe library offers configurable state storage (in-memory or Redis), event hooks for monitoring circuit state changes, and full type annotations. It's designed for distributed systems where shared state across multiple processes is important, and it provides visibility into circuit behavior through monitoring events.","worth_installing":"Yes, if you need circuit breaker functionality for async or sync code. The library is permissively licensed, has no external dependencies, and is fully typed. However, the aging maintenance status (650 days since last release) means you should verify that the library's feature set and behavior match your exact needs before committing to it in a critical system."},"id":"purgatory","links":{"html":"https://skillfed.io/packages/purgatory","md":"https://skillfed.io/packages/purgatory.md","pypi":"https://pypi.org/project/purgatory/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2024-11-02","license_spdx":null,"license_treatment":"permissive","name":"purgatory","python_support":"supports_current","summary":"A circuit breaker implementation for asyncio"},"popularity":{"monthly_downloads":582192,"position":5901,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.0.1"}
