The Python SDK for Apache Beam provides a simple, powerful API for building batch data processing pipelines in Python.
Get started with the Beam Programming Guide to learn the basic concepts that apply to all SDKs in Beam. Then, follow the Beam Python SDK Quickstart to set up your Python development environment, get the Beam SDK for Python, and run an example pipeline.
See the Python API Reference for more information on individual APIs.
Python is a dynamically-typed language with no static type checking. The Beam SDK for Python uses type hints during pipeline construction and runtime to try to emulate the correctness guarantees achieved by true static typing. Ensuring Python Type Safety walks through how to use type hints, which help you to catch potential bugs up front with the Direct Runner.
When you run your pipeline locally, the packages that your pipeline depends on are available because they are installed on your local machine. However, when you want to run your pipeline remotely, you must make sure these dependencies are available on the remote machines. Managing Python Pipeline Dependencies shows you how to make your dependencies available to the remote workers.
The Beam SDK for Python provides an extensible API that you can use to create new data sources and sinks. Creating New Sources and Sinks with the Python SDK shows how to create new sources and sinks using Beam’s Source and Sink API.
