RoadMap

2024

2024: Improve RobustMQ MQTT and enhance the basic capabilities of RobustMQ.

• Enhance the functionality of RobustMQ MQTT.
• Improve the stability and performance of the metadata service, Placement Center.
• Conduct stress tests on RobustMQ MQTT and optimize performance.
• Conduct stress tests on Placement Center and optimize performance.
• Improve test cases for RobustMQ MQTT and Placement Center.
• Enhance the official website and technical documentation of RobustMQ.
• Look for friends interested in Rust or middleware to build a great foundational software together.

2025 H1

Placement Center

Goal: Stable operation of Placement Center in cluster mode, performance testing, and completion of monitoring metrics.

Features

1. Observability
   • Add monitoring metrics for Placement Center.

Improvements

1. Improve cluster capabilities to ensure stable operation in cluster mode.
   • Ensure stable operation of GRPC interfaces in cluster mode.
   • Ensure stable operation of GRPC interfaces during Leader switching.
   • During Leader switching, pause the Controller on non-Leader nodes and run the Controller on the Leader node.
2. Conduct performance testing on the Placement Center service.

Robust MQTT

Goal: Complete the first phase, ensuring stable operation of RobustMQ MQTT in cluster mode. Optimize existing functional code, improve test cases, and add some features.

4. Subscription
   • Optimize subscription process to automatically discard messages without subscriptions
   • Automatic subscription
5. Observability
   • Improve Metrics
   • Integrate with otel
6. Develop a throttling module (for request count, connection count, traffic, etc.)
7. Other
   • Address connection jitter

Dashboard

1. Complete the framework for the Dashboard.
2. Implement linkage between the Dashboard and MQTT Broker's Admin-related interfaces.

Testing

1. Improve unit tests for publishing-related code.
