i did a quick check and looks like tableau pushes calculations to Database.
check in log file "My Tableau Repository"> Logs > tabprotosrv_1.txt (or tabprotosrv.txt),
scroll to bottom and you could find sql tableau is running. this contains calculated column with the logic added in calculation.
Just trying to understand more, so if i have a published a data source with calculated field and when i will refresh my data source two things will happen:
1. Data source will create a session to refresh it self
2. calculate field will also push a session to recalculate it value?
am i correct ?
i guess calculation would be part of session created to refresh data.
tableau included calculated field as a column in Sql and pass it to database, as far as i understand it would be 1 session.
where can i check the log file for that ?
