Mosquitto vs RSMQ: What are the differences?

## Key Differences Between Mosquitto and RSMQ

1. **Protocol Support**: Mosquitto primarily focuses on MQTT protocol for efficient messaging between machines, whereas RSMQ implements a simple Redis-based message queue protocol for communication.

2. **Persistence Mechanism**: Mosquitto stores message data on disk to ensure message persistence even during server restarts, whereas RSMQ relies on Redis for message storage, providing a highly scalable and in-memory storage mechanism.

3. **Scalability**: Mosquitto is capable of handling thousands of clients and messages efficiently, making it suitable for large-scale deployments, while RSMQ is designed to be a lightweight queue system, ideal for applications where simplicity and speed are prioritized over handling massive loads.

4. **Message Priority**: Mosquitto does not natively support message prioritization, treating all messages equally, whereas RSMQ allows developers to set priority levels for messages, ensuring critical tasks are processed first.

5. **Monitoring and Management**: Mosquitto provides extensive monitoring and management capabilities through built-in tools and plugins, enabling administrators to track system performance and troubleshoot issues effectively. In contrast, RSMQ lacks advanced monitoring features, requiring developers to rely on external tools for in-depth insights.

6. **Community Support**: Mosquitto benefits from a large and active community of developers and users, offering a wide range of resources, plugins, and extensions for customization and integration. On the other hand, RSMQ, being a more specialized solution, has a smaller but dedicated community focused on enhancing its core functionalities.

In Summary, Mosquitto and RSMQ differ in protocol support, persistence mechanism, scalability, message priority, monitoring capabilities, and community support, catering to distinct messaging and queuing requirements in various applications.

What is Mosquitto?

It is lightweight and is suitable for use on all devices from low power single board computers to full servers.. The MQTT protocol provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for Internet of Things messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers.

What is RSMQ?

tl;dr: If you run a Redis server and currently use Amazon SQS or a similar message queue you might as well use this fast little replacement. Using a shared Redis server multiple Node.js processes can send / receive messages.
