    What are QVD Files?

    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.

    What are TDE Files?

    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.

    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

  • Extracting data from Tableau hyper files

    As Tableau technology partner we are constantly working on improving our ETL software integration with Tableau
    tableau partner

    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 source
    This applies to 64bit versions only.

    reading tableau data

    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

  • Migrating from QlikView to Tableau

    Here how our customers use Advanced ETL Processor for data migration

    tableau partner
    Converting QVD files to TDE files

    The largest QVD file has 22 million records and it is 5.9 gigabytes in size

    Files

    Using Advanced ETL Processor 64 bit and latest tableau SDK (9.2)

    QVD To TDE 64

    It took 36 minutes to convert the data with an average speed of 10k per second.

    Notes:

    1. Performance depends on a number of factors: Hardware, hard disk performance, number of fields and the complexity of transformations
    2. 32-bit version slightly slower for the file's creation
    3. Always use the 64-bit version with large QVD's

  • Tableau hyper upload testing

    The problem

    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.

    Tableau hyper upload

    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.

    Tableau hyper upload execution log

    The solution

    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.
