New Eventstream sources: MQTT, Solace PubSub+, Azure Data Explorer, Weather & Azure Event Grid 

Eventstream is a data streaming service in Fabric Real-Time Intelligence, enables users to ingest, transform, and route real-time data streams from multiple sources into Fabric. We’re expanding Evenstream’s capabilities, and making real-time data integration even more seamless, by introducing five new source connectors and additional sample data streams. 

With these new connectors, you can easily ingest and process streaming data from a broader range of sources, unlocking new opportunities for analytics and automation.

New Eventstream sources

  • MQTT connector: Connect to an MQTT broker, subscribe to specific topics, and stream data from those topics into Eventstream.
  • Solace PubSub+: Read messages from a Solace PubSub+ Event Broker cluster and stream them into Eventstream for real-time processing.
  • Azure Data Explorer (ADX): Streams data from an Azure Data Explorer database into Fabric in real time.
  • Real-time Weather: Ingest live weather data for a selected city into Eventstream, including temperature, humidity, and wind speed.
  • Azure Event Grid namespace: Stream MQTT, IoT, or any messages from an Azure Event Grid namespace into Eventstream.
  • Sample data streams: Kickstart your streaming projects with additional pre-built sample streams, including real-time bus tracking data and S&P 500 stock market data.

Where to find these new sources?

You can access them in the Get-data wizard in both Eventstream and Real-time Hub. Here’s a screenshot of the new connectors in the wizard. 

Get started today!

These new connectors unlock a world of possibilities for real-time data integration and analytics. To learn more about real-time streaming and processing in Fabric Eventstream, be sure to check out: Fabric Eventstream – overview.
