The Astro Python SDK is an open-source Python framework designed to simplify the process of writing data pipelines in Apache Airflow for data engineers and scientists, especially those with basic Python knowledge. It streamlines the creation of directed acyclic graphs (DAGs) by reducing the typical complexity and boilerplate code associated with standard Airflow operations, requiring knowledge of only seven Python functions and two classes. The SDK's key benefits include shorter and simpler DAGs, database-agnostic and filesystem-agnostic task writing, and automatic orchestration management. It focuses primarily on extract, load, and transform (ELT) pipelines and introduces functions like `load_file` and `transform` to efficiently manage data movement and transformation tasks. By using Python objects, the SDK eliminates the need for XCom or temporary tables, thus decluttering code and enhancing the clarity of data transformation logic. The Astro Python SDK is part of the Astro Open Source Software project, licensed under Apache 2.0, and includes comprehensive documentation, tutorials, and resources to assist users in adopting this new method of DAG authoring.
