I am often exporting data from Teradata and would like to steamline working with import GUI. Is there a way to speedup these steps:
Step 1: why Tableau can not remember server name? (not a big deal, just annoying)
Step 3: why Tableau has to connect before data import (takes a while to connect, not useful for custom SQL anyway).
Step 4: what is the purpose of selecting database for custom SQL?
After clicking OK, Tableau show "Creating Connection". Does anyone actually know what Tableau is doing at this point? I don't think there is any data import is going on till next "Import All" click but it takes very long time.
