mqtt.org VS rumqtt

MQTT (optional): If you're aiming for advanced customization, familiarity with MQTT (a lightweight messaging protocol) will be beneficial for communicating between the toy and the server.

The MQTT protocol is widely used in IoT applications because of its simplicity and ability to connect different data sources to applications using a publish/subscribe model. While many MQTT brokers support persistent sessions and can store message history as long as an MQTT client is not available, there may be cases where data needs to be stored for a longer period. In such cases, it is recommended to use a time series database. There are many options available, but if you need to store unstructured data such as images, sensor data, or Protobuf messages, consider using ReductStore. It is a time series database specifically designed for storing large amounts of blob data and optimized for IoT and edge computing.

https://mqtt.org is more popular, but its more complex. You will unlikely write your own mqtt while you can easily write own stomp broker.

I wanted to share my latest package (published on NuGet) implementing the MQTT v5 protocol.

I jumped onto https://mqtt.org/ to try to answer my usual use-case question about non-Kafka messaging, which is: "Do the messages get saved anywhere so you can come back and read them later?" Still not entirely sure about it.

But I did see:

    This is why MQTT has 3 defined quality of service levels: 0 - at most once, 1- at least once, 2 - exactly once

rumqttd is a high performance, embeddable MQTT broker that we wrote in Rust. MQTT is extremely lightweight publish/subscribe messaging transport for the Internet of Things (IoT).

Disclaimer: have not tried it myself. I was, however, considering using it to replace Mosquitto as a broker.

Other crates like https://crates.io/crates/paho-mqtt and https://github.com/bytebeamio/rumqtt are not available for browsers and do not compile to wasm.

Recently lot of new contributors showed interest, as well as contributed to rumqtt, so thank you so much everyone for your support <3 Feel free to discuss anything in comments, if you wish to contribute as well, you can look for `good-first-issues` ( or open new issues here )

GitHub release - rumqttd-0.15.0

there is already an issue open for it: https://github.com/bytebeamio/rumqtt/issues/432. It is something that we would love to have, but not something in priority.

I wanted to let you know that rumqttc, a Rust MQTT client library, now supports several new features in MQTT 5 protocol. If you're not familiar with MQTT, it's a lightweight messaging protocol designed for IoT devices with limited resources.

I know I should have asked this in their issues, but someone already did and didn't get a response. So I was not sure whether to create another issue, or comment in the same one (and not get a response as well?). So I decided to ask on Reddit first, thank you! https://github.com/bytebeamio/rumqtt/issues/598
