Popular MQTT Brokers

There are several popular MQTT brokers available, each with its own set of features and capabilities. Here are some of the most widely used MQTT brokers:


1. **Eclipse Mosquitto:** Mosquitto is a lightweight open-source MQTT broker that is widely used in both small-scale and large-scale deployments. It is written in C and supports various platforms, including Linux, Windows, and macOS. Mosquitto is known for its simplicity, reliability, and ease of integration into different environments.


2. **HiveMQ:** HiveMQ is a scalable and feature-rich MQTT broker designed for enterprise-level deployments. It provides advanced features such as clustering, high availability, and extensive monitoring capabilities. HiveMQ supports MQTT 5.0 and is available in both open-source and commercial editions.


3. **VerneMQ:** VerneMQ is a distributed MQTT broker built on the Erlang/OTP platform. It offers high scalability, fault tolerance, and clustering capabilities. VerneMQ is known for its robustness and ability to handle large-scale MQTT deployments.


4. **RabbitMQ:** Although RabbitMQ is primarily a general-purpose message broker that supports multiple protocols, it also provides MQTT support. RabbitMQ is highly reliable, scalable, and feature-rich, making it suitable for various messaging scenarios, including MQTT-based IoT applications.


5. **IBM Watson IoT Platform:** IBM Watson IoT Platform is a cloud-based IoT platform that includes an MQTT broker as one of its core components. It offers MQTT support along with other IoT-specific functionalities such as device management, data analytics, and integration with other IBM Watson services.


6. **AWS IoT Core:** AWS IoT Core is a managed cloud service provided by Amazon Web Services (AWS) for building IoT applications. It includes an MQTT broker as part of its service offering. AWS IoT Core is highly scalable, reliable, and integrates well with other AWS services for building end-to-end IoT solutions.


These are just a few examples of popular MQTT brokers, and there are many other options available. When choosing an MQTT broker, consider factors such as your specific requirements, scalability needs, deployment environment, ease of integration, and support for security features.


It's also worth noting that some IoT platforms or frameworks provide MQTT broker functionality as part of their offerings. Depending on your overall IoT architecture and requirements, you may find value in using an integrated solution provided by such platforms.

Message Limitation

The maximum length of a publish message on an MQTT topic depends on the MQTT broker implementation and any specific limitations imposed by the broker or the MQTT protocol version being used. The MQTT specification itself does not define a fixed maximum length for the payload of a publish message. However, most MQTT brokers have their own limitations and constraints. In general, MQTT brokers may impose restrictions on the maximum size of a publish message to ensure efficient network usage and prevent abuse or denial-of-service attacks. The maximum length can vary depending on factors such as the available memory on the broker, network limitations, or configuration settings. It is recommended to consult the documentation or specifications of the specific MQTT broker you are using to determine the maximum allowed length for publish messages on topics. The broker's documentation should provide details on any limitations or guidelines regarding the maximum payload size for publish messa...

Overview of MQTT

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for efficient communication between devices in a network. It was developed by IBM in the late 1990s and has since become an open standard maintained by the OASIS consortium. MQTT is designed to be simple and efficient, making it well-suited for resource-constrained devices and networks with limited bandwidth or intermittent connectivity. It follows a publish-subscribe messaging model, where devices communicate by publishing messages to topics and subscribing to topics to receive relevant messages. Here's a brief overview of how MQTT works: Broker: MQTT uses a central message broker, which acts as an intermediary between publishers and subscribers. The broker receives messages published by devices and routes them to subscribers based on their topic subscriptions. Topics: Messages in MQTT are organized into topics, which are hierarchical and represented by strings. Topics can have multiple levels,...

Implement Historical Messages

In MQTT, the broker typically does not store or provide access to historical messages by default. MQTT follows a publish-subscribe model where messages are delivered to subscribers in real-time. However, you can implement a solution to store and retrieve historical messages on a specific topic by using additional components or modifying your MQTT setup. Here are a few approaches: Message Persistence: Configure your MQTT broker to use a message persistence mechanism. Some MQTT brokers, such as Mosquitto, support message persistence options like persistence plugins or configurations. By enabling message persistence, the broker will store messages on disk, allowing you to retrieve historical messages later. External Message Storage: Implement an external database or message queue that subscribes to the MQTT broker and stores messages on a specific topic. You can develop a custom application that connects to the broker, subscribes to the desired topic, and saves the received messages to a ...
