NSQ

Judgement

What it is

Building block

What it does

A distributed message queue made of nsqd brokers, a lookup service for discovery and an admin web UI, designed for high-volume pub/sub without a single broker.

Adopt it when

You need simple, horizontally scaled pub/sub between Go services and can accept at-least-once delivery without ordering guarantees.

Watch out

Development has slowed, with the last release some time ago, and NATS JetStream now covers most of the same ground.
