Hello everyone, I'm exploring the use of GrowthBook for a newly launched website and I'm currently deciding on the best data source or data warehouse to integrate with. Since the website is still in its early stages, I have the flexibility to choose any suitable option. From what I gather, the process involves gathering data through platforms like Google Analytics or Matomo, and then storing this data in a data warehouse, which could even be a Postgres database, for analysis. Importantly, I'm seeking a solution that aligns with EU regulations and allows for complete data control, in compliance with GDPR. Could anyone share some recommendations on this? Thanks in advance!

Depends a bit on what you want from that data- on one end you have Google Analytics, which is super easy to use, and then you have something like Jitsu on the other, which requires you doing more work. GA4 is easiest to connect to a BigQuery database, and Matomo uses MySQL, while some of the others are more flexible. For GDPR, I know both Rudderstack and Jitsu don’t store any data, and rudderstack would be a bit more functional out of the box. I’m assuming the others have european servers - but I don’t know off the top of my head. Having written the data integration for Matomo, I’m a bit concerned with the data structure they chose to use, and how it will scale.

Thanks a lot for the answer. After reading about Jitsu, it sounds amazing. In the GrowthBook docs it reads that there is no tutorial how to use Jitsu as a datasource in GrothBook. Is there any material available so I can get started and figure things out? Did anybody write a explanation yet? Thanks again!

the schema for jitsu is flexible, so the queries you’d create in GrowthBook depend on that
