In case of irregular or missing events, a regular interval output can be generated from a more sparse data input. For conditions that span through multiple events the LAG function can be used to identify the duration of that condition. When performing an operation such as calculating averages over events in a given time window, duplicate events should be filtered. For the examples I’m going to use the health services as a basis for my scenarios. With out-of-the-box integration for Azure IoT Hub and Azure Event Hubs, Azure Stream Analytics … The streaming analytics service need to be able to fetch data from other business databases and combine with streaming data.
