API Stability Preview

The featureFlags() GraphQL query is used to list feature flags depending on filters and context. All flags should be considered as beta features. Enabling features that are marked as experimental is strongly discouraged and can lead to LogScale being in a bad state beyond repair.

Syntax

Below is the syntax for the featureFlags() query field:

graphql
featureFlags(
     includeExperimentalFeatures: boolean, 
     enabledInScopeFilter: EnabledInScope
   ): [FeatureFlagV2!]!

The includeExperimentalFeatures is used to include experimental features. Enabling experimental features can lead to LogScale in a bad state beyond repair.

The example below requests a list of features that have been flagged, including experimental ones. For the return values, it's asking for the name of the flag, whether it's experimental, and a description of it.

     includeExperimentalFeatures: true,

Given Datatypes

The enabledInScopeFilter parameter is used to enable filter defining. With it, you set which scope feature flags should be returned. It uses the EnabledInScope datatype, which has a few parameters that are listed below:

Table: EnabledInScope

ParameterTypeRequiredDefaultStabilityDescription
Some arguments may be required, as indicated in the Required column. For some fields, this column indicates that a result will always be returned for this column.

Disabled   PreviewUsed to disable the feature flag.
GlobalScope   PreviewIndicates the feature flag is enabled globally.
OrganizationScope   PreviewSets the feature flag scope for the organization.
UserScope   PreviewUsed to enable the feature flag for a user.

Returned Datatypes
