Hi team, We’re exploring GrowthBook for feature flag (and experiment in the future). I have a basic question regarding rollout. My understanding is that features and rule information are sent from GB server and will be calculated/processed by client SDK. Let say I want to rollout a feature to only 20% of our users. Who assign which user that will get the feature and who will keep track of it? Thanks! 🙂
apologise for basic question, tried to watch the youtube videos and read the documentation and still couldn’t figure it out

Hi Fajar, Usually it is assigned randomly to your users. When you select the rollout, you choose what user attribute you are randomizing by.
more specifically, we will create a hash of the feature name, and the user attribute your targeting, and get a value from 0 to 1. If you are targeting 20%, we’ll only show the feature to users who get a value <= 0.2
