NSQ: Open-source realtime distributed messaging, billions of messages / day

Billions of messages per day is 10-100k per second on average. If you do this in a vertical on one box with something like a ring buffer abstraction, you can achieve MPSC messaging rates in excess of millions per second without trying very hard across any arbitrary # of clients.<p>E.g. <a href="https:&#x2F;&#x2F;aeron.io&#x2F;aeron-open-source&#x2F;#aeron_transport" rel="nofollow">https:&#x2F;&#x2F;aeron.io&#x2F;aeron-open-source&#x2F;#aeron_transport</a>

When you would use this over Kafka, Pulsar, Kinesis, NATS, RedPanda, Fluvio, etc.?<p>I found this comparison from 2023 <a href="https:&#x2F;&#x2F;gcore.com&#x2F;learning&#x2F;nats-rabbitmq-nsq-kafka-comparison&#x2F;" rel="nofollow">https:&#x2F;&#x2F;gcore.com&#x2F;learning&#x2F;nats-rabbitmq-nsq-kafka-compariso...</a>

This project has been around for a long time. I made a few contributions in like 2014 or 2015. It is a great distributed stack and a semi-comfortable alternative to things like RabbitMQ. Did something new happen?

Used NSQ a bunch at an old job, it was simple and reliable, never gave us any trouble, at the scale of, yes, billions of messages per day.

how is this different from zeromq, rabbitmq?
