QVD is a native Qlik format and can only be written to and read by Qlik Sense or QlikView. The file format is optimized for speed when reading data from a script but it is still very compact. Reading data from a QVD file is typically 10-100 times faster than reading from other data sources.

The TDE data file format is used by Tableau Desktop, a whiteboard visualization and analysis application. It may contain data extracted from external sources such as Microsoft Excel and Microsoft Access. TDE files are used for storing external data in a format recognized by the Tableau software.

Support for Hyper files was introduced in Tableau 10.5. Since then a lot of our users asked how to converter existing TDE transformation to Hyper. This video tutorial explains how it can be done in less than a minute
Other changes are:
Tableau is a business intelligence software that allows anyone to connect to data in a few clicks, then visualize and create interactive, sharable dashboards with a few more. It's easy enough that any Excel user can learn it, but powerful enough to satisfy even the most complex analytical problems. Securely sharing your findings with others only takes seconds.
The result is BI software that you can trust to actually deliver answers to the people that need them.
Once Advanced ETL Processor completes transformation it might take a while for Tableau API to finish processing. This is normal behaviour
A Tableau data extract file (TDE ) is a compressed snapshot of data stored on disk and loaded into memory as required to render a Tableau viz.
All versions of Advanced ETL Processor support Tableau TDE files as a data-target
Here is a screenshot of the Advanced ETL Processor generating TDE file:

We're excited to announce that, through the Hyper API integration our ETL software can now read Tableau Hyper Data Extract (.hyper) files as a data sourceThis applies to 64bit versions only.
The ability to extract data from Hyper files opens a number of interesting opportunities to our customers: for example, it is now possible to convert Tableau Hyper files to QlikView QVD files
The largest QVD file has 22 million records and it is 5.9 gigabytes in size
Using Advanced ETL Processor 64 bit and latest tableau SDK (9.2)
One of our customers was having problems publishing tableau hyper files to the tableau online server. We asked them to grant us access. That was given and we started our testing. Here is the package we created. It has a loop object which is executed 40 times. The package uploads various hyper files. The file sizes are between 800k and 150mbs.
It takes 2.5 hours to execute the packages. During execution, the files are published non-stop about 400+ times. The package failed in our office several times but it was constantly falling on the customer site. We created 11 internal releases before we managed to fix the problem.
There were not specific failure patterns. All development was done according to API published by Tableau.
So what wee did is introduced more resilience.
Advanced ETL Processor will try to connect the tableau server 5 times and once successful it will attempt to upload the files up to 3 times.
We offer free 30 days trial of our ETL Software, no registration is required. You can create Hyper and TDE files. It is also possible to run SQL against hyper files and extract data from them.
