With an heavy data volume and the objective of building reports and dashboards for the executive comitee, just asking if there is a Talend connector or any another way the extract data from the Matomo Database to build a Datawarehouse usable with our Qlik reporting system.
Thank’s for your answer
Hello Sebastien,
Hope the answer wasn’t too late 
We did this integration via API calls to live visits and refined the data using Talend.
It worked in the end but there is a lot of work to do in UI traffic setup and in the Qlik measures calculation as well when defining how to calculate these numbers.
If you have more questions don’t hestitate.
Honestly, I had a similar setup once, and it was a headache trying to get everything to flow smoothly
