Azure Data Explorer (ADX) is a fully managed, high-performance, big data analytics platform that makes it easy to analyze high volumes of data in near real-time. The Azure Data Explorer toolbox gives you an end-to-end solution for data ingestion, query, visualization (including third-party dashboards), and management.
ADX can ingest data both from (persisted) storage and data provided as a stream:
Ingested data is managed and optimized by the underlying cluster so it can be queried and made available in (third-party) platforms as a view (like Power BI, Grafana, etc.) based on a powerful query language.
Data can also be ingested directly from Azure IoT Hub, as a stream for real-time analysis.
These events are emitted by the Azure IoT Hub as routing events next to the regular incoming device-to-cloud messages. Routing these device lifecycle events makes it possible for both persisting and reacting at the behavior of devices (creation, deletion, connected, disconnected) and registration changes (device identity twin changes).
This was first demonstrated using a regular direct internet-connected device.
