Introduction
Navigating an Azure Data Factory Interview can be a daunting process, especially for those aspiring to specialize in cloud data integration solutions. Azure Data Factory (ADF) is a cornerstone of modern data architecture in the Microsoft Azure ecosystem, making knowledge about it crucial for many IT professionals. This article aims to prepare candidates with everything they need to know for an interview focused on Azure Data Factory.
Understanding Azure Data Factory
What is Azure Data Factory?
Azure Data Factory is a cloud-based data integration service that allows users to create, schedule, and orchestrate data workflows. These workflows can move and transform data from various sources to various processing platforms and data stores, using a wide array of on-premises and cloud-based ETL and data integration services.
Key Components of Azure Data Factory
ADF operates with several key components including:
- Integration Runtime (IR): The compute infrastructure used by ADF to provide data integration capabilities across different network environments.
- Pipelines: A logical grouping of activities that together perform a task.
- Activities: Tasks that run in your pipeline, such as moving data or transforming data.
- Datasets: Representations of data structures within the storage resources, which are used as inputs and outputs for activities in pipelines.
