Query folding Import mode
does query folding happens in case of import mode? if yes then those transformations happens at source or inside power bi memory?
Query folding still works in import mode, so it's important to apply foldable steps first. For example, filtering rows and removing columns can be pushed to the source. Do those steps early, before adding any that stop query folding. Power Query will show a warning when a step breaks folding.
