Hi!
I imported 2 SQL views with 20000rows each into PowerBI Desktop. Then in the query editor I'm trying to merge them together using inner join based on 2 key fields. One is DATETIME data type and other is VARCHAR(50) data type. In the merged table when I try to expand some columns from the merged table it doesn't complete in 2-3 minutes. Shouldn't merge be done in memory? I don't want PowerBI to go back to the SQL views, which indeed are very slow when doing the join there...
Best Wishes,
Kaarel.
