You can release new E-Commerce service features and functionality behind a feature gate. This project uses the Waffle library for feature gating.
Waffle supports the following types of feature gates.
Flag: This gate allows you to enable a feature for specific users, groups, users who meet certain criteria (such as authenticated users or staff), or a certain percentage of visitors.
Switch: This gate is a Boolean that turns a feature on or off for all users.
Sample: This gate allows you to define the probability with which a given feature will be on.
For more information about creating or updating features and feature gates, see the Waffle documentation.
