Legacy Dataset, Evaluation, and Report endpoints are deprecated for new workflows. Use the Tables API for new dataset import, evaluation, scoring, recalculation, and reporting workflows.
Update an existing column on an evaluation pipeline blueprint. Use this to change a column’s configuration, rename it, or move it without recreating the whole pipeline.

​
Behavior Notes

  • Dataset columns are protected and cannot be edited.
  • Only blueprint pipeline columns can be edited; columns on finished batch runs cannot.
  • Column names must remain unique within the pipeline.
  • Editing a column re-queues cells in that column and any columns to its right.
