Have you ever created an import model unsuccessfully because some of the columns from sources cannot be adjusted before importing, or you just basically want to modify your source column to optimize your data workflow?
If that's the case, you're not alone. We have officially enabled Source Expression when creating Import Models. With just a few clicks, you can modify your source expression before it's being loaded in your data warehouse.
Please note that this option is only applicable to database sources (Postgres, MySQL, BigQuery, etc.)
