Is there a solution to connect to Google Analytics ?
Nothing I'm aware of.
an add-on or connector for Google Analytics is a large factor when I/we ultimately land on a long-term ETL platform. I’d really like to hear whether or not this currently exists on the roadmap. If so, when is it expected to be rolled-out?
Google Analytics connector is planned for version 4.0 planned for release in Q2-2018. Note that it won’t be available in the free edition.
