1. Re: Difference between an Extract created from TDE(Published datasource) and from DB
Michael Gillespie Sep 11, 2018 6:49 AM (in response to Rohan Singh)Rohan, let's get our terminology straight first.
1) TDE = Tableau Data Extract. This is Tableau's original format for the Extract file.
2) Hyper = Hyper extract. This is a completely new technology that Tableau acquired. It REPLACES the TDE format and is much more efficient.
So, to answer your question, yes, both TDE and Hyper are extract formats but other than that they are completely different technologies. When you say "they're both extracts" it's like saying Ford and Ferrari are both cars so why is there a performance difference?
Make sense?

Rohan Singh Sep 11, 2018 8:24 AM (in response to Michael Gillespie)It does. But in my case, both are hyper extract(embedded data as well as published datasource).
