Azure Data Explorer for telemetry analytics
Kirkby Robotics collects billions of telemetry records per day from factory machines and needs interactive, ad hoc analysis with KQL, including time-series functions and anomaly detection, with results returned in seconds over months of data. What should you recommend?
- A.Azure Data Explorer
- B.Azure Cosmos DB for Table
- C.Azure SQL Database in the General Purpose tier
- D.Azure Blob Storage with the cool access tier
Show answer and explanation
Correct answer: A. Azure Data Explorer
Why: Azure Data Explorer is designed for fast, interactive analytics over large volumes of telemetry and log data with KQL, including native time-series analysis and anomaly detection functions. A General Purpose SQL database is not built for billions of rows per day of ad hoc telemetry analysis. Blob Storage stores data without a query engine, and Cosmos DB for Table is a key-value store.
