blazingmq VS mosquitto

Sounds great, and you have lots of nice documentation on the page, but could you provide a TLDR? There's a lot of competition in this area: GRPC, Cap'n'proto (was posted on HN a day or two ago), NATS, etc.

I'm also having trouble figuring out if Mats3 is a library (with a JMS API) over a variety of messaging systems (WebSockets, NATS, etc.)?

P.S. Some diagrams like https://bloomberg.github.io/blazingmq/ would be very helpful, especially at https://mats3.io/background/what-is-mats/. If a picture's worth a thousand words, and an animation must be worth at least 10k words. :)

This is a perfect use case for MQTT, e.g. this library for ESP boards. Create a broker on the network (e.g. a Raspberry Pi running Mosquitto, and have all the ESP boards subscribe to a topic. When you want to play a sound, publish a message to the topic, and all of the ESPs should see it very quickly. You don't need to synchronize clocks any more because it's simply based on the timing of publishing a message.

While working on a personal project Komponist, I was due to update Mosquitto MQTT Broker due to a CVE and found some interesting changes that will impact me in the future when it comes to configuring the Broker. This post provides a solution to make the Broker compatible with future versions using new and less visited concepts in Docker Compose v2, namely:

Optional: Mosquitto, an open-source message broker that implements the MQTT protocol; this tutorial uses the public test server

I think he means implementation of MQTT protocol, like https://mosquitto.org/

Could MQTT work for you? You'd need a broker like Mosquitto, and then any of a number of MQTT clients.
