What is Go NSQ?

NSQ is a great distributed queue. I’ve used it successfully as a primary building block for large-scale distributed systems. Here are some of its features:

• Support distributed topologies with no SPOF.
• Horizontally scalable (no brokers, seamlessly add more nodes to the cluster).
• Low-latency push based message delivery (performance).
• Combination load-balanced and multicast style message routing.
• Excel at both streaming (high-throughput) and job oriented (low-throughput) workloads.
• Primarily in-memory (beyond a high-water mark messages are transparently kept on disk).
• Runtime discovery service for consumers to find producers (nsqlookupd).
• Transport layer security (TLS).
• Data format agnostic.
• Few dependencies (easy to deploy) and a sane, bounded, default configuration.
• Simple TCP protocol supporting client libraries in any language.
• HTTP interface for stats, admin actions, and producers (no client library needed to publish).
• Integrates with statsd for real-time instrumentation.
• Robust cluster administration interface (nsqadmin)
