Descripción

Task Summary

Aggregate groups by a column's values, and a timestamp has a different value in almost every row, so grouping by one puts each row in its own group. Nothing in Texera can make the coarser column that grouping wants: sales by month cannot be asked for, though the platform carries a TIMESTAMP type, a Gantt chart and a time-series plot.

An operator that reads the whole-number parts out of a timestamp — year, quarter, month, day, weekday, hour and the rest — closes that. It parses nothing: the column is already a moment by the time it arrives, and which text became which moment was settled upstream, the way KNIME, Alteryx and Spark all separate parsing from extraction.

The parts are read as ISO-8601 states them, since the engine and the exported Python do not agree by default: pandas counts Monday as 0 and java.time counts it as 1.

Not part of #8325: nothing here makes a workflow exportable. It does ship standalone code, so it comes after the trait #8327 introduces, and its parity assertions need the harness that issue builds.
