## 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 reverts a recent change (apache/beam#37847) that introduced an unintended regression in the Dataflow Streaming worker. The original change, intended to isolate commit threads, inadvertently caused the StreamingEngineWorkCommitter to create a new WindmillStreamPool for every commit, leading to inefficient resource utilization. This revert restores the previous behavior, ensuring correct WindmillStreamPool instantiation and resolving the observed performance issue. ### Highlights * **Revert of Stream Pool Isolation**: Undid a previous change that aimed to isolate commit threads by using a separate WindmillStreamPool for each committer. * **WindmillStreamPool Configuration Restored**: Restored the WindmillStreamPool creation to utilize numCommitThreads instead of a fixed value of 1. * **Regression Fix**: Addressed a regression where the previous change caused StreamingEngineWorkCommitter to incorrectly create a new WindmillStreamPool per commit. 🧠**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>Changelog</b></summary> * **runners/google-cloud-dataflow-java/worker/src/main/java/org/apache/beam/runners/dataflow/worker/StreamingDataflowWorker.java** * Reverted the modification to WindmillStreamPool creation, changing the stream pool size from '1' back to 'numCommitThreads'. </details> <details> <summary><b>Activity</b></summary> * Initiated as a direct revert of pull request apache/beam#37847. * Identified a regression where the previous change led to StreamingEngineWorkCommitter creating a new WindmillStreamPool per commit. * Provided a visual aid (screenshot) to demonstrate the impact of the regression. </details> <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>`.
