Using Multivariate Feature Flags In LaunchDarkly To Drive Operational Settings Like Minimum Log Level

LaunchDarkly, a feature flag service provider, has introduced multivariate feature flags that allow engineers to define custom settings. These feature flags can provide Boolean values or an arbitrary set of string values, number values, or a combination of the three. This new feature opens up possibilities for long-term feature flags and helps drive actual site operations. The author demonstrates this concept by creating a multivariate feature flag that changes the minimum log-level being used by a given application.
