What’s new in HiveMQ Edge 2025.9

HiveMQ’s latest Edge release introduces database connectivity support via the new Databases Protocol Adapter, unlocking more advanced data connectivity use cases at the Edge. This release also includes a number of fixes and enhancements to the existing feature set.

Databases Protocol Adapter

Now, users can accomplish more on the Edge with the Databases Protocol Adapter, which enables the querying of databases connected via IP. The adapter supports MySQL, MSSQL, and PostgreSQL connections, and SQL languages.

How it works

Like all HiveMQ Edge Protocol Adapters, users need to define an adapter configuration. For the Database adapter, the endpoint and database type must be configured.

Next, a user needs to create a tag, which is essentially a query to collect the data.

Once a connection is established and tags are created, users can map these to MQTT topics for use in HiveMQ Edge, or publish the data immediately northbound to their MQTT broker.

How it helps

Having the ability to query databases with HiveMQ Edge enables users to unlock more advanced DataOps use cases when utilizing Data Hub on Edge or Data Combinations features to govern and contextualize OT data before sending it downstream.

For example, querying order details such as a "consignment number" allows users to combine that number with real-time sensor data (temperature, pressure, speed) collected during production. By linking the consignment number to sensor data, a traceable connection is established. This integrates sensor readings with order details (customer, destination, instructions), eliminating ambiguity and providing a clear view of the manufacturing and logistics process for that specific consignment. This enhances optimization, troubleshooting, and reporting.

Additional Improvements

• Upgraded HiveMQ DataHub - delivering improved performance and a reduced package size.
• Fixed an issue where sessions were not properly closed, improving resource management and system stability.
