Use Tableau Data Extract as data source

We are working on creating a model using Tableau data extract as data source. The extract is located on a network drive. My question is, does Tableau need to load the entire file before we can consume the data. So if the data extract is 2GB, does it read through the entire 2GB into memory initially.

How about using MS-SQL view as data source? if we are connecting to a view that suppose to take 1 hour to return data without any filter, do we have to wait a hour plus the time to read in all of the return data before we can work on the model?
