## Summary of Changes Hello @Suvrat1629, 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 refines how pipeline transforms are processed within the SDKHarness by implementing topological sorting. This change ensures that operations are executed in their correct dependency order, which is crucial for data processing pipelines. To optimize performance, a caching layer has been added for the computed topological orders. Furthermore, the system is made more resilient by including robust cycle detection and a fallback mechanism that reverts to the prior processing method if any issues arise during topological sorting, ensuring continuous operation. ### Highlights * **Topological Ordering**: Transforms within ProcessBundle in the SDKHarness are now processed using topological ordering, ensuring correct dependency execution. * **Caching Mechanism**: A LoadingCache is introduced to store the computed topological order, keyed by descriptor ID, preventing redundant computations. * **Cycle Detection and Fallback**: The system detects cycles in the pipeline definition during topological sorting. If a cycle is found or the loader fails, it gracefully falls back to the previous descriptor-order processing to maintain stability. * **Enhanced QueryablePipeline**: The QueryablePipeline now includes all relevant Components (coders, pcollections, transforms, windowing strategies) when computing the topological order, ensuring accuracy. * **New Tests**: New unit tests (testTopologicalOrderRespectsDependency, testProcessBundleCreatesRunnersForAllTransformsUsingTopologicalCache) have been added to validate the topological ordering, caching, and fallback behavior. <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>`.
