Edge device detections into Fabric: Eventstream + Eventhouse, or Lakehouse?
Hi all, While working on a computer vision project at DataToBiz, we built the edge side of a real-time system, and I’d like to compare notes with people here on how the data side would work in Fabric. On the edge, the detection runs on a Raspberry Pi. We used YOLOv8n with ByteTrack to track vehicles across frames, plus Depth-Anything-v2 for depth estimation from a single camera so we could apply spacing rules. The model was converted to ONNX, TFLite and NCNN, and we used quantization and threading to get the speed we needed without heavy hardware. A camera, GPS and compass were synced by timestamp, so every detection comes out tagged with its time, location and direction. Post-processing smooths the detections to reduce flickering. That leaves a stream of time-stamped, geo-tagged detection events from many devices, and that’s the part I’d like your input on in Fabric. Would you ingest it through Eventstreams into an Eventhouse and query it with KQL, or land it in a Lakehouse and process it in batches? Where does that line sit for you when the end goal is near real-time dashboards? How do you handle devices that go offline and send their events late or out of order? Do you rely on event time in the Eventhouse, or clean it up downstream? For the geo side, with coordinates and direction on every event, how have you handled spatial queries and map visuals in Real-Time Intelligence or Power BI? Is it good enough, or do you still end up pre-processing the coordinates? And with raw detections arriving continuously, how do you decide what to keep as raw events, and what to aggregate into something like per-location availability for reporting? Would love to hear how you’d approach it.
Azure Maps base layer not loading in Real-Time Dashboard - Only points visible
Hi Fabric Community, I'm experiencing an issue with Map visualizations in Real-Time Dashboards. The data points are rendering correctly, but the Azure Maps base layer (streets, terrain, satellite) is not loading - only a white/blank background appears. **Environment:** - Microsoft Fabric Real-Time Intelligence - Real-Time Dashboard with KQL queries - Eventhouse as data source - Browser: Chrome/Edge (tested both) - Region: South Central US **Steps to reproduce:** 1. Create a KQL query with latitude/longitude columns 2. Add to Real-Time Dashboard 3. Change visual type to "Map" 4. Configure: Latitude column, Longitude column, Label column 5. Points appear but no map background **What I see:** - Colored circles representing my 10 GPS devices - Correct relative positions between points - Zoom controls (+/-) present but don't show map tiles - "Center" button works for positioning **What I expected:** - Azure Maps base layer with streets/roads visible behind the points **Troubleshooting attempted:** - Tried different browsers (Chrome, Edge) - Cleared browser cache - Verified coordinates are correct (Mexico City area: 19.5, -99.3) - Checked browser console - no obvious errors **Questions:** 1. Is there a known issue with Azure Maps in Real-Time Dashboards? 2. Are there specific tenant/admin settings required for Azure Maps? 3. Is this a preview limitation? Screenshots attached showing points without map background. Thank you for any guidance!
