## 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 significantly enhances the performance of the Iceberg `AddFiles` operation by introducing parallel processing capabilities. By leveraging a thread pool within the `ConvertToDataFile` DoFn, the system can now concurrently handle multiple incoming data files, thereby reducing bottlenecks associated with sequential file I/O and metadata operations. This change optimizes resource utilization and accelerates the overall data ingestion process into Iceberg tables. ### Highlights * **Asynchronous File Processing**: Implemented asynchronous processing of incoming data files within the `ConvertToDataFile` DoFn to improve performance. * **Thread Pool Integration**: Introduced an `ExecutorService` (thread pool) to parallelize latency-bound operations such as file I/O, catalog lookups, and metadata inference for multiple files concurrently within a single DoFn instance. * **DoFn Lifecycle Management**: Refactored the `ProcessElement` method to submit file processing tasks to the thread pool and added a `FinishBundle` method to await the completion of all tasks in the current bundle and safely emit results. * **Result Encapsulation**: Created a new `ProcessResult` internal class to encapsulate the outcome of each file's processing, including the `SerializableDataFile` or any error `Row`, along with its timestamp and window. 🧠**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](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <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>`.
