Hi ,

QlikView data eXchange (QVX) is a file/stream format for high performance data input into QlikView.

A QVX formatted file contains metadata describing a table of data and the actual data. In contrast to

the QVD format, which is proprietary and optimized for a minimum of transformations inside

QlikView, the QVX format is public and free to use.

Please refer the below attachment

Hi,

A QVX formatted file contains metadata describing a table of data and the actual data. In contrast to the QVD format, which is proprietary and optimized for mininum transformations inside QlikView, the QVX for- mat is public and requires a few transformations when exporting data from traditional data base formats. QVX files are loaded in the script with the load statement. This file type has no configurable settings.

It is a data protocol published and supported by Qlik.

With the Qlik APIs you can design data source files in QVX format and also create data connectors that will transform source data into QVX for Qlik to consume.  Many excellent partners of QLIK use the protocol to expose new data sources to QLIK.

QVD is a closed format; however it improves the speed that data can be brought into Qlikview. Now we have QVX these are externally exposed, and supplement QVD files. QVX is used in the Extract Transform Load (ETL) process as it is reloaded.  QlikView will connect allowing one document to handle multiple ODBC connections, and it also allows a 64 bit QlikView to a 32 bit ODBC driver. QVX stream allows QlikView to handle multi threaded load or connect statements, making better use of hardware available.
