Types ¶
type Factory ¶
type Factory struct {
FactoryConfig
// contains filtered or unexported fields
}
Factory implements samplingstrategy.Factory interface as a meta-factory for strategy storage components.
func NewFactory ¶
func NewFactory(config FactoryConfig) (*Factory, error)
NewFactory creates the meta-factory.
func (*Factory) CreateStrategyProvider ¶
func (f *Factory) CreateStrategyProvider() (samplingstrategy.Provider, samplingstrategy.Aggregator, error)
CreateStrategyProvider implements samplingstrategy.Factory
func (*Factory) InitFromViper ¶
InitFromViper implements plugin.Configurable
func (*Factory) Initialize ¶
func (f *Factory) Initialize(metricsFactory metrics.Factory, ssFactory storage.SamplingStoreFactory, logger *zap.Logger) error
Initialize implements samplingstrategy.Factory
type FactoryConfig ¶
type FactoryConfig struct {
StrategyStoreType Kind
}
FactoryConfig tells the Factory what sampling type it needs to create.
func FactoryConfigFromEnv ¶
func FactoryConfigFromEnv() (*FactoryConfig, error)
FactoryConfigFromEnv reads the desired sampling type from the SAMPLING_CONFIG_TYPE environment variable. Allowed values: * `file` - built-in * `adaptive` - built-in
