## Summary of Changes Hello @shunping, I'm Gemini Code Assist[^1]! 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 extends the Apache Beam Python SDK examples by adding a batch version of the `OrderedWindowElements` PTransform. This new component enables users to process data within defined windows, ensuring elements are ordered by timestamp and providing flexible strategies to handle data gaps. It leverages Beam's state and timer features to generate context for filling empty windows or gaps at the beginning of windows, offering robust control over data continuity in batch pipelines. ### Highlights * **New Batch Implementation**: Introduces `batch.py` containing the `OrderedWindowElements` PTransform, designed for batch processing, complementing an existing streaming version. * **Windowing and Gap Filling Logic**: Adds several `DoFn` classes (`FanOutToWindows`, `FanOutToSlideBoundaries`, `GenerateContextDoFn`, `WindowGapFillingDoFn`) to manage element assignment to windows, generate context for gaps, and intelligently fill those gaps. * **Configurable Gap Strategies**: Implements a `WindowGapStrategy` enum (with options like `IGNORE`, `DISCARD`, `FORWARD_FILL`) to define how empty windows and gaps at the start of windows are handled. * **Comprehensive Testing**: Includes `batch_test.py` with parameterized unit tests covering various windowing configurations, offsets, slide intervals, and all defined gap-filling strategies to ensure correctness. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
