we want to start testing a new feature. We want to proceed very cautiously and initially only include 10% of the user base (with a 50:50 split). If we see after 1-2 days that there are no problems, we want to roll it out to 30% of the user base, and so on.
What is the best approach here? For example, can we use a namespace and adjust it during the experiment?
Looking forward to your feedback. Thank you in advance 🙏

Hi Tanja. We support this use case without needing to use namespaces

set the overall exposure to 10% with a 50/50 split
