PyMySQLLock

PyMySQLLock is a Python library that provides a MySQL-backed distributed locking primitive. It enables multiple application instances to coordinate and ensure that only one instance holds a specific lock at a time, performing tasks that require exclusive access. As of version 0.2.0, it aims to be a lightweight solution when MySQL is the primary dependency for application uptime and health, rather than relying on external systems like ZooKeeper or etcd. The project appears stable with a moderate release cadence.
