What is TDE file?

A TDE file is a Tableau desktop file with the .tde extension. It is a file that contains data retrieved from external sources such as Microsoft Excel, Microsoft Access, or a CSV file. TDEs are useful for aiding analytics and data discovery due to two elements of their architecture. To begin with, TDE is a columnar database. The second factor is how they are organized, which has an influence on how Tableau loads them into memory and uses them. This is a crucial part of TDEs’ “architecture awareness.” TDEs that are architecture-aware employ all components of your computer memory, from RAM to hard drive, and put each element to work in the most appropriate way for its characteristics.
