Azure Data Factory (ADF) is an enterprise-grade, fully managed cloud data integration service used for orchestrating complex ETL (Extract, Transform, Load) and ELT workflows. By providing a scalable, serverless execution environment, it allows data engineers to construct automated pipelines that ingest data from diverse sources and route it through various transformation engines. While the visual authoring interface is intuitive, truly mastering ADF requires a deep understanding of dynamic pipeline parameterization via Expressions, leveraging the distributed processing power of Mapping Data Flows, and selecting the correct Integration Runtime topology for secure and performant data movement.
