What is QVX ?? Do we have any real world use case for this??

Hi Experts

Please help with real-world experience using QVX files kindly share some insights into their use cases?

Additionally, if there are any relevant documentation or resources available on this topic, I'd greatly appreciate it if you could share them as well.

Thank you!

@henrikalmen  Hey, I've checked out the post you recommended, but it seems a bit dated. That's why I've posted again. Do you use QVX files? If so, what specific use case have you employed them for? Also, if there are any recent resources or documentation you could point me to, I'd really appreciate it!

To understand QVX you need first to understand what a QVD is. QVD is a data file optimized for Qlik and can only be read and written from/to Qlik. If you consider the potential of Qlik to create a kind of file-based data warehouse, QVDs have a problem, since other technologies would not be able to consume or produce QVDs.

That is where the idea of QVX came. It is like a QVD, but you can use APIs to read and write.

It was not a great success because, while it is possible to use it outside of Qlik, it is not as simple and other technologies never implemented specific connectors that will make this simpler.

The best strategy would be for Qlik to use another type of fast and optimized data file that is already used by the industry. Now we have that with parquet. You can read and write parquet files with Qlik and basically any other relevant technology. It is smaller than a QVD and still really fast.

I am already replacing the use of QVDs to Parquet in my new projects and it is working great.
