Azure Data Explorer is a managed, high-performance data exploration service specifically designed for analyzing log and telemetry data. This article explains what Azure Data Explorer is, when to use it, and how it integrates with other Azure services. You will also become familiar with the Kusto Query Language (KQL), the key tool for querying data stored within the service.

​
Overview

Azure Data Explorer operates through a simple three-step process:
  1. Create a Data Explorer cluster and an associated database in Azure.
  2. Ingest data from a variety of sources.
  3. Query the ingested data using KQL.
For more detailed insights into setting up your Data Explorer cluster, please refer to the Azure Data Explorer Documentation.
