Redsync
Redsync is a distributed lock manager and Go Redis client extension designed to ensure exclusive access to shared resources. It implements mutual exclusion across multiple processes by using a Redis backend to coordinate synchronization and prevent race conditions in distributed environments.
The library maintains lock validity through quorum-based consensus, requiring successful writes to a majority of independent Redis nodes. It utilizes Lua-scripted atomic operations for acquisition and release, while employing value-based ownership validation and time-to-live expiration to prevent deadlocks.
The project provides capabilities for distributed coordination and application synchronization, utilizing client-side retry polling to manage resource acquisition timeouts.
