Are Feature rollouts randomized?

Hello,

 

I wanted to confirm whether the percentage rollouts of Features in Optimizely is applied randomly to visitors. From the docs, I know that they share the bucketing logic of Experiments, but I wanted to make sure here since the docs don’t specifically mention randomization.

 

Thanks!

Re: Are Feature rollouts randomized?

Hi there,

 

That's correct. From our documentation:

 

"Feature rollouts use bucketing logic to evaluate traffic allocation. The logic combines the user ID and a unique rollout ID to compute a deterministic hash that outputs a number between 0 and 10,000. If that number falls within the range specified by the feature rollout’s traffic allocation, the visitor is eligible for the feature."
