Functions ¶
func NewFeatureLabService ¶
func NewFeatureLabService(featureLabClient featurelab.FeatureLab) pb.FeatureLabServer
Types ¶
type CacheableFeatureLabClient ¶
type CacheableFeatureLabClient struct {
// contains filtered or unexported fields
}
func NewCacheableFeatureLabClient ¶
func NewCacheableFeatureLabClient(featureLabHost string, ttl, cleanUpInterval time.Duration) *CacheableFeatureLabClient
func (*CacheableFeatureLabClient) FetchFeature ¶
func (f *CacheableFeatureLabClient) FetchFeature(app string, featureName string) (featurelab.Feature, *featurelab.Error)
FetchFeature fetches the Feature information of a Feature from the Feature Lab backend service and stores it in cache, overwriting any value that already exists in the cache with the same Feature Treatment.
func (*CacheableFeatureLabClient) FetchFeatures ¶
func (f *CacheableFeatureLabClient) FetchFeatures(app string) ([]featurelab.Feature, *featurelab.Error)
FetchFeatures fetches all features from the Feature Lab backend service and stores them in cache, overwriting any values that already exist in the cache with the same Feature names.
func (*CacheableFeatureLabClient) GetTreatment ¶
func (f *CacheableFeatureLabClient) GetTreatment(app string, featureName string, criteria string) (featurelab.TreatmentAssignment, *featurelab.Error)
GetTreatment calculates the treatment that is assigned for a criteria in a particular Feature stored in the cache. If the Feature is not in the cache, then featurelab.FeatureOff is returned. This method won't make calls to the backend service, it will only operate on features stored in cache. To force a cache update, you must call FetchFeatures (to cache all features) or FetchFeature (for a specific Feature).
func (*CacheableFeatureLabClient) UpdateCache ¶
func (f *CacheableFeatureLabClient) UpdateCache() *featurelab.Error
type FeatureCache ¶
type FeatureCache interface {
GetFeature(app, name string) (featurelab.Feature, bool)
PutFeature(app, name string, feature featurelab.Feature)
PutFeatures(features []featurelab.Feature)
}
func NewDefaultFeatureCache ¶
func NewDefaultFeatureCache(ttl time.Duration, cleanUpInterval time.Duration) FeatureCache
type FeatureLabService ¶
type FeatureLabService struct {
pb.FeatureLabServer
// contains filtered or unexported fields
}
func (*FeatureLabService) FetchFeature ¶
func (fls *FeatureLabService) FetchFeature(ctx context.Context, fetchFeatureRequest *pb.FetchFeatureRequest) (*pb.FetchFeatureResponse, error)
func (*FeatureLabService) FetchFeatures ¶
func (fls *FeatureLabService) FetchFeatures(ctx context.Context, fetchFeaturesRequest *pb.FetchFeaturesRequest) (*pb.FetchFeaturesResponse, error)
func (*FeatureLabService) GetTreatment ¶
func (fls *FeatureLabService) GetTreatment(ctx context.Context, getTreatmentRequest *pb.GetTreatmentRequest) (*pb.GetTreatmentResponse, error)
