Azure Data Explorer, also known as Kusto, is a big data analytical database service designed for near-real-time insights into scalable log analytics, time series analytics, and IoT/telemetry analytics on Azure. The blog post outlines a process to integrate event streaming from Apache Kafka on Confluent Cloud into Azure Data Explorer using the Kafka Connect Kusto Sink Connector. Kafka Connect is an open-source, distributed integration service that simplifies data streaming between sources and sinks without requiring code, supporting features such as fault tolerance and per-record transformation. The post provides detailed instructions for setting up a streaming pipeline, including creating a Confluent Cloud instance, configuring Azure Data Explorer, and deploying Kafka Connect on Azure Kubernetes Service. It also highlights the use of Docker and Helm for managing connector infrastructure and encourages participation in the open-source project, offering a promo code for additional Confluent Cloud usage.
