As far as I can tell, you can only push data from an event hub to power bi through a streaming analytics query that uses a windowing grouping (tumbling, hopping, and sliding windows). Even if you set a window to 1 second refresh, the possibility always exists that more than 1 event can be grouped into that window. When that has happened to me, I'm not able to get specific data on either of the events that come through that window. Data comes through, but I don't know what event it refers to because it only creates one row of data for all events. For example, my count field will show that >1 events took place, but there aren't specific details for each event. There is just one row of data that corresponds to both events. I'm happy to provide further clarification if needed. Ultimately, I'd like for data that enters my event hub to be sent through the streaming analytics job to Power BI in real time and each data point given its own unique row.
