Musxeto opened a new issue, #5854: URL: https://github.com/apache/texera/issues/5854
### Feature Summary ### Feature Summary Currently, the Aggregate operator only supports `SUM`, `COUNT`, `AVERAGE`, `MIN`, `MAX`, and `CONCAT`. It lacks common statistical aggregations such as Median, Variance, Standard Deviation, and Mode. Adding these functions will provide data scientists with more powerful statistical tools out-of-the-box when building workflows. ### Proposed Solution or Design 1. Add `MEDIAN`, `VARIANCE`, `STDDEV`, and `MODE` to `AggregationFunction.java`. 2. Implement the computation logic for these functions in `AggregationOperation.scala` (and any related distributed aggregation classes). 3. Update the frontend UI schema for the Aggregate operator to reflect the new options. 4. Add comprehensive unit tests in `AggregateOpSpec.scala` covering positive, negative, and edge cases. ### Affected Area Workflow Engine (Amber), Workflow UI -- This is an automated message from the Apache Git Service.
