Create a mechanism for resetting the cache for the data lineage


Create a mechanism for resetting the cache for the data lineage

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.

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.

The second half that you described is a big annoyance for us - if you generate multiple QVDs from the same script, each QVD gets cumulative lineage and makes it much more difficult to read than necessary (and as mentioned can increase file size unnecessarily).
