Optimizing Azure Data Explorer for Large-Scale IoT Telemetry Data

Azure Data Explorer (ADX) is a fast, fully managed analytics database optimized for high-volume streaming data like IoT telemetry. In energy and smart city scenarios, ADX can ingest millions of sensor readings and provide sub-second analytical queries. This overview covers schema design best practices, performance tuning, delta (incremental) querying, cost considerations, and how ADX compares to other time-series solutions.
