Healthcare data is high-volume, high-stakes, and structurally complex: ADT events, lab results, vitals streams, medication records, and billing codes all arrive continuously and need to be queryable in real time for clinical operations, quality reporting, and population health. ClickHouse handles the volume and latency that healthcare analytics requires.

IoT deployments generate time-series telemetry at a rate that most databases can't ingest and query simultaneously. Thousands of devices reporting every second, anomaly detection that needs to run in real time, and dashboards that need to show fleet-wide metrics without scanning terabytes of raw readings. ClickHouse is built for exactly this pattern.
