Define Tableau Data Engine?

Tableau Data Engine is a fantastic component of the software. It’s an analytical database that promises rapid query response, predictive performance, easy integration with current data infrastructure, and the ability to load whole data sets into memory. It takes some time to import, generate indexes, and sort data if you deal with a huge quantity of data, but everything accelerates quickly after that. Tableau Data Engine isn’t actually an in-memory database. After the data is imported, it is saved to disc, and RAM is barely used.
