Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request cherry-picks changes that enhance the determinism of Apache Beam's Python SDK. It addresses potential flakiness in tests related to external transform configurations and ensures consistent output when generating cross-language wrappers, ultimately improving the reliability and reproducibility of the build process.

Highlights

• Deterministic Test Comparison: Introduced a normalization step in the external transform configuration test to sort configurations before comparison, preventing non-deterministic test failures.
• Deterministic Wrapper Generation: Ensured deterministic generation of cross-language wrappers by sorting discovered transforms and their configuration parameters.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
