Azure Data Explorer
Azure Data Explorer (ADX) is a fully managed, high-performance data analytics service in Microsoft Azure designed for real-time analysis of large volumes of streaming data. It uses a columnar storage format and a powerful query language called Kusto Query Language (KQL) to enable fast ingestion and querying of telemetry, logs, and time-series data. It is commonly used for log analytics, IoT telemetry, and monitoring scenarios.
Developers should learn Azure Data Explorer when working with large-scale, real-time data analytics, especially for use cases like application monitoring, IoT device telemetry, and security log analysis. It is ideal for scenarios requiring rapid ingestion and querying of streaming data, such as operational intelligence, where traditional databases may struggle with performance. Its integration with Azure services like Azure Monitor and Azure IoT Hub makes it a key tool for cloud-native analytics solutions.
