Hi Dominic,
You can use Feature Flags without a data warehouse, but to run Experiment Analyses you will need to set up a data warehouse. You could choose to use
any provider that we currently support.
We don't have any tools or docs to help you get your data from Contentful into a data warehouse, though, because we don't currently have a Contentful integration. After having brainstormed with the Contentful team about it, it would be quite a big undertaking to create one, so itβs not currently on our product roadmap.
