## Summary of Changes Hello @stankiewicz, 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 enhances the Apache Beam Java SDK's timer mechanism by introducing a `causedByDrain` flag. This flag allows `DoFn`s to distinguish between timers that fire as part of normal pipeline execution and those that are explicitly triggered during a pipeline draining process. By propagating this information through the core timer interfaces and their implementations, it provides more granular control and context for `DoFn`s reacting to timer events, which is crucial for robust pipeline shutdown and data consistency during draining. ### Highlights * **Propagate 'causedByDrain' Flag**: Introduced a `boolean causedByDrain` parameter to the `DoFnRunner.onTimer` method and `TimerInternals.TimerData` to indicate if a timer firing was triggered by a draining operation. * **DoFn Context Updates**: Added `causedByDrain()` abstract methods to `DoFn.ProcessContext` and `DoFn.OnTimerContext` to expose the drain status to user `DoFn` logic. * **Extensive Integration**: Updated numerous `DoFnRunner` implementations, `TimerData` factory methods, and `Timer` utility classes across various runners (Core Java, Flink, Dataflow, Samza, Spark) and SDK components to correctly pass and handle the new `causedByDrain` flag. * **Test Coverage**: Modified existing test cases to accommodate the new `causedByDrain` parameter in `TimerData.of` and `Timer.of` calls, ensuring consistency and 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>`.
