Integrate MQTT and Kafka with Redpanda Connect

IntroductionCopied!

ContextCopied!

In modern data pipelines, seamless integration of different messaging systems is crucial to support real-time analytics and decision-making. Two widely adopted technologies in this space are MQTT, commonly used in IoT and device communication, and Apache Kafka, the go-to platform for scalable data streaming and processing. Integrating these systems allows businesses to unlock the full potential of real-time data across their infrastructure.

Problem StatementCopied!

Historically, open source connectors have made it relatively simple to bridge MQTT and Kafka. However, with the discontinuation and reduced support for these connectors, organizations now face significant hurdles in maintaining a smooth data pipeline. This gap threatens data flow, adds operational complexity, and increases costs, making it essential to find a reliable alternative.

Solution OverviewCopied!

Redpanda Connect emerges as a powerful alternative, filling the void left by traditional open source connectors. It provides an efficient, user-friendly, and robust way to integrate MQTT with Kafka-like capabilities, ensuring your data pipeline remains strong and future-ready.

BackgroundCopied!

What is MQTT?Copied!

MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe messaging protocol designed for low-bandwidth, high-latency, or unreliable networks. Its simplicity and efficiency make it the protocol of choice in IoT and embedded systems, enabling reliable communication between devices and services.

What is Kafka?Copied!

Apache Kafka is an open-source, distributed streaming platform designed for high-throughput, fault-tolerant data pipelines. It excels in real-time data processing and event-driven architectures, making it a backbone for scalable applications in industries such as finance, e-commerce, and telecommunications.

Past Integration MethodsCopied!

Open source connectors like the Kafka Connect MQTT Source Connector were previously used to integrate MQTT with Kafka. These connectors handled the translation and data flow seamlessly, enabling developers to focus on business logic instead of integration challenges.

Challenges with the Discontinuation of Open Source ConnectorsCopied!

Impact on Current SystemsCopied!

For businesses that depended on open source connectors, the end of support means immediate disruption. Data that once flowed freely between MQTT and Kafka may now be at risk of bottlenecks, data loss, or integration errors.

Operational ChallengesCopied!

Without a supported connector, maintaining a reliable bridge between MQTT and Kafka becomes challenging. Teams must grapple with:

  • Inconsistent data delivery
  • Increased latency in data flows
  • Manual management of topic mappings and translations

Cost and ComplexityCopied!

Building and maintaining a custom integration is expensive. Development teams need to invest significant time and resources into crafting a robust, scalable, and fault-tolerant solution — an effort that distracts from core business activities.

Introducing Redpanda ConnectCopied!

What is Redpanda?Copied!

Redpanda is a modern streaming data platform that offers a Kafka API-compatible experience with better performance, lower latencies, and no reliance on JVM. Built in C++, it’s designed for high throughput and predictable performance — ideal for low-latency, real-time data pipelines.

Redpanda ConnectCopied!

Redpanda Connect is an integration framework built to replace traditional Kafka Connect connectors and streamline the flow of data between various protocols and Redpanda. For MQTT and Kafka use cases, Redpanda Connect acts as the missing link — enabling direct, high-performance integration.

Benefits of Using Redpanda ConnectCopied!

  • Reduced Latency: Faster data processing compared to JVM-based Kafka Connectors.
  • Simplified Integration: Out-of-the-box support for MQTT and other protocols.
  • Operational Efficiency: No need to build and maintain custom solutions.
  • Enhanced Reliability: Robust error handling and seamless topic mapping.

How to Achieve Integration Using Redpanda ConnectCopied!

Step-by-Step GuideCopied!

1. Setup Redpanda Environment

  • Deploy a Redpanda cluster using either Docker, Kubernetes, or bare-metal setups.
  • Verify cluster health using Redpanda’s built-in observability tools.

2. Configuring Redpanda Connect

  • Access the Redpanda Connect UI or CLI to configure MQTT as a data source.
  • Set up the MQTT broker connection details (host, port, authentication if needed).
  • Define the data flow (which topics to consume and publish to).

3. Mapping Topics

  • Map MQTT topics to Redpanda topics within Redpanda Connect.
  • Apply any necessary transformations to ensure schema consistency and compatibility.

4. Monitoring and Maintenance

  • Leverage Redpanda’s built-in observability stack to monitor data flows.
  • Set up alerts for connection issues or processing errors.
  • Regularly review topic mappings and data volumes to optimize performance.
