Redlock - A ruby distributed lock using redis. Distributed locks are a very useful primitive in many environments where different processes require to operate with shared resources in a mutually exclusive way. There are a number of libraries and blog posts describing how to implement a DLM (Distributed Lock Manager) with Redis, but every library uses a different approach, and many use a simple approach with lower guarantees compared to what can be achieved with slightly more complex designs.
