  • Can Tableau handle 1 million rows?

    To reduce rows, consider filtering and aggregating your data.
    This could be done in the database, in Tableau Desktop's Data Source window, or with a data preparation tool like Tableau Prep or Alteryx.
    One common change is limiting the extract to just the relevant time period by applying a Data Source filter..

  • How much GB of data that Tableau can handle?

    Workbooks, published data sources, and flows count toward this storage capacity.
    Individual workbook, published data source, and flow size: An individual workbook, data source (live or extract), or flow published to your site can have a maximum size of 15 GB..

Jul 18, 2014The answer is no. The compression used to reduce the storage requirements of a TDE to make them more efficient is not file compression. Rather, 
A Tableau data extract is a compressed snapshot of data stored on disk and loaded into memory as required to render a Tableau viz. The data extracts can be scheduled on the Tableau Server to refresh automatically.
Compress Tableau Size Ultimately a twbx is just a zip file that contains both the workbook and the data, so these files are just about as compressed as they 

How does tableau work?

As Tableau retrieves data, it sorts, compresses and adds the values for each column to their respective file.
With 8.2, the sorting and compression occur sooner in the process than in previous versions, accelerating the operation and reducing the amount of temporary disk space used for extract creation.

Why does tableau use a TDE file?

Because a TDE is a memory-mapped file, when Tableau requests data from a TDE, the data is loaded directly into memory by the operating system.
Tableau doesn’t have to open, process or decompress the TDE to start using it.
