Manage tenant feature toggles via features.json

Within every Tenant code repository can exist a features.json file that extends the default Marfeel Platform values of a feature toggle. This can be used to enable or disable a feature toggle for a specific tenant, effectively overriding the default Marfeel Platform values.

Some usage examples could be:

1. Enable an experiment on a tenant
2. Disable a rolled out feature for a specific tenant

The format of the tenant features.json is exactly the same as the Marfeel features.json and the same features json schema (opens new window) is used during compile time for validation.

Inheritance

As with all other json configuration files in the Marfeel Platform, a tenant features.json extends a Marfeel features.json file. At runtime the different SDKs will resolve the value of a certain feature toggle through the following chain (first that returns a value returns and stops the chain):

1. cookie-sticky toggle
2. Tenant features.json set via code or via MarfeeInsight UI
3. Marfeel default features.json value
