BifroMQ

English | 中文简体

BifroMQ is a high-performance, distributed MQTT broker implementation that seamlessly integrates native multi-tenancy support. It is designed to support building large-scale IoT device connections and messaging systems, Currently, it serves as the foundational technology for Baidu IoTCore, a public serverless cloud service.

Features

Full support for MQTT 3.1, 3.1.1 (MQTT5 support coming soon) features over TCP, TLS, WS, WSS
Native support for multi-tenancy resource sharing and workload isolation
Built-in storage engine. Optimized for critical load targeting, no third-party middleware dependencies
Extension mechanism for supporting:
- Authentication/Authorization
- Runtime Setting
- Bridging
- Event
- System/Tenant-level Monitoring

Getting Started

Prerequisites

JDK 17+
Maven 3.5.0+

Build from source

Clone the repository to your local workspace:

cd <YOUR_WORKSPACE>
git clone https://github.com/baidu/bifromq bifromq

Navigate to the project root folder and execute the following commands to build the entire project:

cd bifromq
mvn wrapper:wrapper
./mvnw -U clean package

The build output consists of several archive files located under /build/build-bifromq-starters/target/

bifromq-<VERSION>-windows-standalone.zip
bifromq-<VERSION>-standalone.tar.gz

Running the tests

Execute the following command in the project root folder to run all test cases, including unit tests and integration tests. Note: The tests may take some time to finish

mvn test

Deployment

BifroMQ has three deployment modes: Standalone, Standard Cluster, Independent Workload Cluster

Standalone

The standalone deployment mode is ideal for the development stage or production environments that do not require immediate recovery from downtime.

To start a standalone bifromq server, extract bifromq-xxx-standalone.tar.gz into a directory. The directories are like:

|-bin
|-conf
|-lib
|-plugins

Execute the following command in the bin directory:

start server:

./standalone.sh start // the server process will start in background

stop server:

./standalone.sh stop

The configuration file, 'standalone.yml', is located in the conf directory. Many of the settings are self-described via name. By default, the standalone server will save persistent data in data directory.

Standard Cluster(Will be available publicly soon)

The standard cluster deployment mode is suitable for small to medium-sized production environments that require reliability and scalability. It comprises several fully functional nodes working together as a logical MQTT broker instance, ensuring high availability. You can also scale up the concurrent mqtt connection workload by adding more nodes, while some types of messaging related workload are not horizontal scalable in this mode.

Independent Workload Cluster

The Independent Workload Cluster deployment mode is designed for building large-scale, multi-tenant serverless clusters. In this mode, the cluster consists of several specialized sub-clusters, each focusing on a particular 'independent type' of workload. These sub-clusters work together coherently to form a logical MQTT broker instance. This is the most complex deployment mode and requires additional non-open-sourced building blocks.
