Instead of adding external systems like Zookeeper or etcd, it leverages your existing MySQL infrastructure to ensure only one instance holds a lock at a time and can execute protected tasks.\n\nThe package exposes a Locker class that takes standard MySQL connection parameters, then creates named Lock objects that can be acquired with optional timeouts and released when done. It maintains the lock by periodically pinging the MySQL connection in the background to prevent idle disconnection. You can also query all currently held locks on the database.","worth_installing":"No. The package is abandoned (last release 2020-09-13, no maintenance since) and classified as pre-alpha. While the concept is sound and the MIT license is permissive, the lack of updates means no fixes for bugs, compatibility issues with modern Python or MySQL versions, or security concerns. Consider a maintained alternative like a Redis-based lock library or a purpose-built distributed coordination tool unless you have a very stable, isolated deployment and can accept the risk of no future support."},"id":"pymysqllock","links":{"html":"https://skillfed.io/packages/pymysqllock","md":"https://skillfed.io/packages/pymysqllock.md","pypi":"https://pypi.org/project/pymysqllock/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2020-09-13","license_spdx":null,"license_treatment":"permissive","name":"PyMySQLLock","python_support":"supports_current","summary":"MySQL Backed Locking Primitive"},"popularity":{"monthly_downloads":255021,"position":8485,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
