It's wierd that this information was removed like his page on https://learn.microsoft.com/en-us/power-query/query-folding-basics :
Theoretically, couldn't Microsoft translate adding an index into something that does fold into a native query? E.g. something like this pattern:
SELECT
[...]
ROW_NUMBER(ORDER BY [...]) AS index
FROM [...]
While it's not currently implemented this way, is there anything fundamentally preventing indexing from being folded into a native query?
This would be very helpful to add surrogate integer keys without processing every row within Power Query.
