QViewer ver.3.3 is out

QViewer version 3.3 is now available for downloading. Here is what's new and exciting in the new version:

Support for QVD files larger than 2GB
Now you can open QVD files basically of any size. It was tested on QVD files up to 20GBs. Technically, at this point the only limitation is 2 billion rows per file. QViewer aggressively parallelize calculations so you may want to give it some time to perform necessary counts after opening a large file, because during that time CPU utilization can be near 100% which would make the application less responsive.

New Partial Load workflow
In the new version the workflow for partial load was significantly changed. The Partial Load button has been removed. Instead, when a file larger than certain threshold is opened QViewer suggests  performing a partial load (see the screenshot below). The threshold can be set at 512MB, 1GB, 2GB, 4GB or 8GB.

Indication of metrics affected by partial load
When a partial load is performed some metrics calculated by QViewer can be distorted because the loaded dataset is incomplete. To avoid confusion QViewer now shows which metrics are affected by partial load (shown red) and which are not.

Comments in generated script
When generating a LOAD statement, QViewer can now insert field comments obtained from the XML header. These comments are typically created using COMMENT FIELD or COMMENT TABLE statements in QlikView / Qlik Sense before exporting a table into QVD file.

UPDATE 4/23/2017
I'm considering further improvements to QViewer. The ideas are floating around a few topics: table inspection for Qlik Sense Server, [shareable] selection bookmarks, support for other file formats (e.g. QVX, CSV, or XLSX), aggregation with built-in pivot tables (with selections applied). However, I'm not sure what would be the most useful for the Qlik dev community. I would appreciate hearing it from you -- what would you like to see in future versions of QViewer? Feel free to send me your suggestions (see my email in the upper right corner of this blog), or just leave a comment below.
