      How the aggregated TDEs are work. For example if i create the aggregated TDE, will it add aggregated in addition to regular data(Least granular data).

          Hi siva Nageswara Rao,


          Answer: Yes

          Details: A TDE - Tableau Data Extracts - are highly optimised, highly compressed, subsets of your data stored in a columnar database file. When you connect to data using Tableau you can either connect ‘Live’ or you can extract the data into a .tde. Data extracts are used to radically improve performance, particularly when connecting to slow databases or slow files (e.g. CSVs), as well as enabling additional functionality.
