A job worker solution that is robust, concurrent and highly available for Node.js using redis.
This is a robust concurrent and highly available job solution, derived from an idea of Flickr's article: Highly Available Real Time Push Notifications and You.
RedisPaidWorker backups any tasks with high availability in two different processes, which maybe in a different server or even a different data center.
var redis = ;var RedisPaidWorker = ;var config =lockTimeout: 100firstAttemptInterval: 10otherAttemptInterval: 30;var redisClient = redis;var worker = config;worker;// lock using redis' hashworker;
RedisPaidWorkertry to acquire same lock but either will win; another will stay.
npm install redis-paired-worker
RedisPairedWorker.hlockto use redis' hash for locks.
