This blog post introduces the concept of multi-language pipelines using Apache Beam. It explains how to leverage I/O connectors and transforms from different languages in your favorite language without reinventing the wheel. The post provides a step-by-step guide with a working demo of a Python pipeline reading and writing data from/to the Java FireStoreIO connector. It covers the implementation of required interfaces in Java, setting up a local expansion service, and building the Python pipeline. Although multi-language pipelines are still in early development and have limitations, this blog post offers a starting point for creating such pipelines.
