Often the index of a dataset or small changes to its schema needs to be changed, but the recipe that builds that dataset takes many hours to run. Ideally, there would be a way to make changes to the index and schema in-place. In SQL, this is typically done by copying data to a temporary table, then reinserting it into the original table with the changes.
If Dataiku could automate this process, it would save many hours loading data when this kind of change is needed on large tables.
