OpenFeature review

[joshgav]

Presented to TAG App Delivery by @toddbaert on 2022-05-04.

• Web site: https://openfeature.dev/
• Code: https://github.com/open-feature
• Spec (WIP): https://github.com/open-feature/spec/tree/main/specification
• Specifies a common API to be implemented (possibly via conversion) by a service provider like LaunchDarkly and others.
• One SDK per language can work with either a) native OpenFeature API or b) any service provider via provider plugins for the SDK (compare to OpenTelemetry exporters).
• No implementations of spec as an API service for now. Maybe in the future.
• SDK allows adding additional “hooks” at time of checking flags
• SDK as a sidecar via operator extracts logic from actual apps into CRDs: https://github.com/open-feature/feature-operator
• Q: Why something specific to feature flags rather than a general configuration management system? Is “feature flags” a special case of general config mgmt?
  • Feature flags must be evaluated dynamically, at run time. Config management systems handle more static info, compare to ConfigMaps.
