Constants

const (
	// SamplingTypeEnvVar is the name of the env var that defines the type of sampling strategy store used.
	SamplingTypeEnvVar = "SAMPLING_CONFIG_TYPE"
)

Variables

var AllSamplingTypes = []string{samplingTypeFile, samplingTypeAdaptive}

AllSamplingTypes lists all types of sampling factories.

Types

type Factory

type Factory struct {
	FactoryConfig
	// contains filtered or unexported fields
}

Factory implements strategystore.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) AddFlags

func (f *Factory) AddFlags(flagSet *flag.FlagSet)

AddFlags implements plugin.Configurable

func (*Factory) CreateStrategyStore

func (f *Factory) CreateStrategyStore() (strategystore.StrategyStore, strategystore.Aggregator, error)

CreateStrategyStore implements strategystore.Factory

func (*Factory) InitFromViper

func (f *Factory) InitFromViper(v *viper.Viper, logger *zap.Logger)

InitFromViper implements plugin.Configurable

func (*Factory) Initialize

func (f *Factory) Initialize(metricsFactory metrics.Factory, ssFactory storage.SamplingStoreFactory, logger *zap.Logger) error

Initialize implements strategystore.Factory

type FactoryConfig

type FactoryConfig struct {
	StrategyStoreType Kind
}

FactoryConfig tells the Factory what sampling type it needs to create.

func FactoryConfigFromEnv

func FactoryConfigFromEnv(log io.Writer) (*FactoryConfig, error)

FactoryConfigFromEnv reads the desired sampling type from the SAMPLING_CONFIG_TYPE environment variable. Allowed values: * `file` - built-in * `adaptive` - built-in

type Kind

type Kind string

Kind is a datatype holding the type of strategy store.
