To standardize a few activation strategies, we also needed to standardize the Unleash context, which contains fields that vary per request, required to implement the activation strategies.
The Unleash context is composed of a set of predefined fields. The static fields do not change in the life-time of your application, while dynamic fields can change per feature toggle evaluation.
Static context fields
- appName: String
- environment: String
Dynamic context fields
- userId: String,
- sessionId: String,
- remoteAddress: String,
- properties: Map<String, String>
All fields are optional, but if they are not set you will not be able to use certain activation strategies. E.g., the userWithId strategy obviously depends on the userId field.
The properties field is more generic and can be used to provide more arbitrary data to strategies. Typical usage is to add more metadata. For instance, the betaUser strategy may read a field from properties to check whether the current user is a beta user.
In Unleash Enterprise you may also pre-configure all you customer context fields (properties) and use them together with strategy constraints to compose any target rules you need.
