Hi all.
I have several huge source table (>20 GB) , and I need to create new table with unic values from [Column 1].
I create new query with List.Combine(Table1[Column1], Table2[Column1]) and several transformation. After Apply changes, PBI upload source tables several times: for main data and for created lists.
Is it possible to reduce number of uploads source tables?
As a source of raw tables I use dataflows.
Solved! Go to Solution.
@Denis_Slav , Can you try this DAX and see if saves time.
distinct(union (all(Table1[Column1]), all(Table2[Column1])))

Thanks. Didn't think in this direction. )
But in that case I have no possibility to transform data. (
@Denis_Slav , yes, but Power query kind of works on the complete table. so once you are done with all data modeling you can try this.
