FAQ

Questions Feature Flag Rollout Calculator owners ask.

  • 01

    How does the user assignment work?

    The get_user_assignment capability uses consistent hashing of the User ID and Feature Key to ensure that a user's assignment remains deterministic at any given rollout percentage.

  • 02

    Can I use this for A/B testing?

    Yes. You can use calculate_statistical_thresholds to determine the necessary sample size to detect a specific Minimum Detectable Effect (MDE) with your desired confidence level.

  • 03

    How do I estimate the impact of a multi-stage rollout?

    Use project_rollout_impact by providing your total population size and a schedule of percentages to see both active and incremental user counts at each stage.
