LaunchDarkly has added native Redis feature store support to its .NET SDK, providing a persistent store for feature flag configurations. The Redis feature store can be used in two ways: with a regular connection to LaunchDarkly or with the LaunchDarkly Relay Proxy in daemon mode. In both scenarios, the feature flags are stored in Redis and retrieved using an in-memory read-through cache for improved performance. The Redis feature store is available as a separate NuGet package and its source code is published online. This addition complements the existing Redis support across all other server-side SDKs offered by LaunchDarkly.
