NATS VS mosquitto

Several message brokers, such as NATS and database queues, are not supported by OpenTelemetry (OTel) SDKs. This article will guide you on how to use context propagation explicitly with these message queues.

I guess I don't need to know what it is

During our interview, we referred to NATS quite a few times! If you want to learn more about it, Sebastian suggests this tutorial series.

Pueue dumps the state of the queue to the disk as JSON every time the state changes, so when you have a lot of queued jobs this results in considerable disk io. I actually changed it to compress the state file via zstd which helped quite a bit but then eventually just moved on to running NATS [1] locally.

Imagine you have an AI-powered personal alerting chat assistant that interacts using up-to-date data. Whether it's a big move in the stock market that affects your investments, any significant change on your shared SharePoint documents, or discounts on Amazon you were waiting for, the application is designed to keep you informed and alert you about any significant changes based on the criteria you set in advance using your natural language. In this post, we will learn how to build a full-stack event-driven weather alert chat application in Python using pretty cool tools: Streamlit, NATS, and OpenAI. The app can collect real-time weather information, understand your criteria for alerts using AI, and deliver these alerts to the user interface.

Why wasn't NATS[1] used ?

Written in Go, single-binary deployment... there's a lot to love about NATS !

require nats.io

About cost, see [1]. Also, S3 prices have been increasing and there's been a bunch of alternative offers for object store from other companies. I think people in here (HN) comment often about increasing costs of AWS offerings.

Distributed systems and consensus are inherently hard problem, but there are a lot of implementations that you can study (like Etcd that you mention, or NATS [2], which I've been playing with and looks super cool so far :-p) if you want to understand the internals, on top of many books and papers released.

Again, I never said it was "easy" to build distributed systems, I just don't think there's any esoteric knowledge to what S3 provides.

I am in a project were nats.io is used. Someone thought, it would be a great idea to link data in an event with data in a response using the response channel name.

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.

MQTT is a message broker that's used commonly in IoT (internet of things). This is from all of one week's experience, so take it with a grain of salt, but it's a publisher/subscriber model where each device defines some channels (like openevse/wh openevse/amp etc) and then publishes its stats to an MQTT broker like Mosquitto. Then other services (I've tried it with HomeAssistant and openHAB) pull in the values to store them, drive automations, etc. OpenEVSE also subscribes to input channels that can control it, so I've seen people set up things like 'only allow the charger to run when my pool heater is not running'.
