Hi there! If I do a % roll out for my feature flag, where can I find the list of users that belongs in the roll out group?

I dont think we log those users

ah ok, so I want to A/B test this feature, but I would need to know who these users are in order to run behavioral analysis on our product analytics tool (amplitude). What kind of tools do u guys have to help me achieve that?

so your concern is that if people were previously exposed to the rollout

no actually i just want to see if there's a difference in behaviour between group A with feature flag on, and group B with feature flag off But i can only do the analysis on amplitude, so i need a way to figure out who is in group A

oh I see

Hey Graham! Do you have docs on how to correctly use the hashing algorithm for this kind of use case? i.e. what inputs should we be passing in?

sure - if you want to build your own, the docs are here: https://docs.growthbook.io/lib/build-your-own#private-isincludedinrolloutseed-string-hashattrib[…]rage-float--null-hashversion-integer--null-boolean
