    How much detail would you like?

    Practical

    Feature stores can facilitate reuse and consistent deployment; benefits and effort depend on the project.

    Hypothetical example: Several forecasting models use the same versioned definition for “last 30 days sales”.

    SMEs should only invest in reused, time-critical features and multiple models.
