qlobber-fsq

A shared file system queue for Node.js that supports pub-sub and work queues with AMQP-like topic wildcards. Version 14.0.0 (stable, maintained as of 2025) targets Node 16+. It leverages the local file system for multi-core use and tested distributed file systems (BeeGFS, CephFS) for multi-host setups. Key differentiators vs. Redis pub-sub or RabbitMQ are zero external dependencies beyond Node.js, optional direct producer-to-subscriber streaming (since v12.1.0), and optional shared-memory Disruptor acceleration (since v9). Limitations: no guaranteed message ordering unless using order_by_expiry; best-effort delivery under crashes.
