moat-mqtt 0.42.4

Async MQTT broker and client, with optional MoaT-KV support

MoaT-MQTT is an open source MQTT 3.1.1 client and broker implementation. It is a fork of hbmqtt with support for anyio and MoaT-KV.

MoaT-MQTT provides a straightforward API based on coroutines, making it easy to write highly concurrent applications.

Deprecation Notice

MoaT-MQTT will be retired because by now, broker support for MQTT 5 is nearly universal.

The designated replacement is mqttproto.

Features

MoaT-MQTT implements the full set of MQTT 3.1.1 protocol specifications and provides the following features:

• Support for QoS 0, QoS 1 and QoS 2 messages flows

• Client auto-reconnection

• Authentication via password file (more methods can be added through a plugin system)

Moat-MQTT? DistMQTT? MoaT-KV? Whatever?

MoaT-MQTT is a Python package that includes a stand-alone MQTT server, as well as basic client scripts. It is based on hbmqtt and was previously named “DistMQTT”.

MoaT-KV is a distributed key-value storage system. It uses the MoaT-MQTT client library as its connector to an MQTT server, preferably Mosquitto or some other low-latency broker. It was previously named “DistKV”.

A MoaT-MQTT server can hook into MoaT-KV so that some messages are persisted, translated (i.e. store msgpack messages encoding True and False, instead of the strings “on” and “off” (or “ON” and “OFF” or “1” and “0” or …)), filtered (e.g. the client can only modify existing messages but not add any), et al..
