Where can I find the latest QVX SDK to download?

[SaturnV]

Hi all,

where can I download the latest .NET QVX SDK / QVXLibrary?
There is documentation everywhere but no way to download the SDK.

I can't find it on the Qlik download page, with Google, with ChatGPT or anywhere in the documentations...

Thank you!

Best regards

Hi @SaturnV,

This is the material I found about QVX SDK:
https://help.qlik.com/en-US/sense-developer/November2024/apis/Qvx%20Sdk/html/N_QlikView_Qvx_QvxLibra...

https://help.qlik.com/en-US/sense-developer/November2024/Subsystems/QVXSDKAPI/Content/Sense_QVXSDKAP...

Qlik Sense .NET SDK is something else and you can start here:

Question: Why are you looking for QVX? What is your user case?

Hi @marksouzacosta,

thanks for your reply. I actually mean the QVX SDK...
To use the library: QlikView.Qvx.QvxLibrary

Yes your two first links are the documentation to that SDK. But where can I find the actual SDK?
Like why do we have a documentation to an SDK we can not download?
I have an old version of this Library (dll) from a few years ago. I just wanted to get the latest version. But I cant find anything...

I am extracting data from a MSSQL database and transform the data in a .NET C# application. At the end I need to provide the data to Qlik. And I do that via a QVX file that will be created with C#.

Best regards

Hi @SaturnV,

I did some deeper research and looks like the SDK is not available to download anymore. I'm checking with Qlik to make sure, but this may take some days.
@Øystein_Kolsrud do you have any information about that? Can you help us?

Meanwhile, how about using other formats such as CSV or - preferably - Parquet? Does it need to be QVX?

Hi @marksouzacosta,

i chose QVX because I thougt that will bring us the best performance, as QVX is a Qlik optimized file system.
Or is this not relevant anymore? Will a CSV give us the same performance?
I mean from a C# perspective that would be easier to implement.
What is the best practice today? (From a performance perspective as we have a lot of data)

Thanks and regards

Sorry, but not a topic I'm familiar with I'm afraid.

QVD and Parquet have the best performance and compression in Qlik - Parquet is even better than QVD in multiple scenarios. So, if your data is not large - I mean, over millions of records - CSV should be fine. Otherwise, I would definitely go to Parquet. There is a very popular Nugget Package for C#: https://github.com/aloneguid/parquet-dotnet

One important note: Parquet is supported by the latest releases of Qlik Sense on-prem and Qlik Cloud. I'm not sure about QlikView.

I would not use QVX and I would not recommend it unless for a very very specific case.

Hey @marksouzacosta,

thanks for the answer. I will definitely take a look at parquet 🙂
We are actually using QlikSense currently so this would fit.

Best regards
