ioredfour

A Redis binary semaphore (distributed lock) using ioredis. v1.4.1 is the latest stable release. Forked from redfour, it replaces node_redis with ioredis for better performance and supports Redis Cluster (including sharded pub/sub for release notifications). It implements a lock with configurable TTL, minimum replication count, and replication timeout. Active development, low release cadence.
