From raw data to insights: How to ingest data from Azure Event Hubs into KQL database for powerful analytics

Synapse Real-Time Analytics in Microsoft Fabric is a fully managed big data analytics experience optimized for streaming and analyzing real-time data. In this blog post, we’ll learn about the integration between Azure Event Hubs and your KQL database.
One of the components of Real-Time Analytics is the Kusto Query Language (KQL) Database, a fast, powerful, scalable, and highly available tool that is designed to handle large volumes of data in real time. With its simple yet powerful syntax, KQL allows anyone to query, analyze, and visualize data to get insights in real-time. This allows, for example, businesses to quickly respond to changes in their operations and make informed decisions based on the latest data.
One of the key benefits of KQL Databases is its ability to ingest data from a wide range of sources, including Azure Event Hubs, making it easy to get data into the service and start analyzing it.
Azure Event Hubs is a big data streaming platform and event ingestion service that can process and direct millions of events per second with low latency. Event Hubs represents the “front door” for an event pipeline, often called an event ingestor in solution architectures. An event ingestor is a component or service that sits between event publishers and event consumers to decouple the production of an eventstream from the consumption of those events. Event Hubs provides a unified streaming platform with a time retention buffer, decoupling event producers from event consumers.

With the new integration, you can ingest data directly from Azure Event Hubs into your KQL database, which is useful when you already have an Azure event hub streaming data, and you want to analyze the data in real-time. Using Azure Event Hubs, you can easily bring data from endless sources including devices and sensors, applications, logs and metrics, and Azure cloud resources.
The integration between Azure Event Hubs and KQL Database is straightforward, utilizing a friendly wizard to ingest data.
