Create a mechanism for resetting the cache for the data lineage

i_shamaev — Fri, 15 Nov 2024 23:50:53 GMT

Hello everyone!
We have described a problem with the Qlik Sense Data lineage tool - Data-Lineage-in-Qlik-Sense-needs-to-improve-Current-feature. And I would like to propose to modify the tool so that there is a command that would reset the data lineage cache.

For example,

reset data lineage;

or another.

Due to the fact that we receive data in a loop through the Rest connector, we get large empty files. Also, such metadata (hundreds or thousands of lines) is of no use.

Thanks

Thank you

If you run one Transform application with multiples data transformation steps, then the last saved QVD will contain all the steps for all files processed in this Transform. That is, every tab in the Qlik Sense script prepares 1 QVD file from many other sources (qvd, database, Excel, etc.). On each tab, it would be logical to reset the cache of data lineage.

Upvoted 1000 times. This is such a huge problem when you use the REST connector with a big request body. If you have to loop, the problem gets out of hands rapidly. 44MB after 20 iterations for a <1 MB data file.
