ewd-qoper8

ewd-qoper8 is a high-performance, memory-based message queue for Node.js, currently at version 3.18.1. It manages a pool of persistent child worker processes, each handling one message at a time, to prevent concurrent processing. The queue dispatches JSON messages to available workers, scaling worker count based on demand. Unlike general-purpose queues like Bull or Kue, ewd-qoper8 is designed for minimal overhead and is integrated with the ewd.js ecosystem. It supports customisation of master/worker logic and database connections. Release cadence is low; last stable release was in 2020.
