mop VS mosquitto

While Pulsar has its own protocol that handles streaming, queues, and a lot of the other features (distributed transactions, functions, etc.), it can also speak other messaging protocols via plug-ins. Looking around, the ones that appear to be actively developed are MQTT, Kafka (so your existing applications that use Kafka can also use Pulsar), AMQP, and JMS.

If you need a highly available broker you can consider https://github.com/streamnative/mop which adds a MQTT protocol handler to Apache Pulsar.

I recently contributed auth support and TLS support also just landed.

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.
