## Summary of Changes Hello, 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 introduces the foundational infrastructure required for multi-key execution in Dataflow streaming. By updating the execution context, scheduler, and reader iterators, the changes enable the system to process multiple keys within a single bundle. These modifications are primarily structural, setting the stage for future PRs that will implement the specific failure handling and queue polling logic required for full multi-key support. ### Highlights * **Refactored StreamingModeExecutionContext**: Added support for multi-key execution by introducing methods like startForNewKey and advance, allowing the context to manage state transitions between keys in a single bundle. * **Updated StreamingWorkScheduler**: Refactored the scheduler to handle multi-key work batches, updating execution signatures and processing logic to support batch-level cleanup and statistics recording. * **Enhanced Iterator Logic**: Updated WindmillReaderIteratorBase and WindowingWindmillReader to support key chaining, enabling the iterator to transition seamlessly between keys during work advancement. * **Failure Propagation**: Added an onFailureListener to the Work class to improve failure propagation and cleanup across multi-key execution cycles. <details> <summary><b>New Features</b></summary> 🧠You can now enable **Memory** (public preview) to help **Gemini Code Assist** learn from your team's feedback.
