Types

type Aggregator

type Aggregator interface {
	// Close() from io.Closer stops the aggregator from aggregating throughput.
	io.Closer

	// RecordThroughput records throughput for an operation for aggregation.
	RecordThroughput(service, operation string, samplerType model.SamplerType, probability float64)

	// Start starts aggregating operation throughput.
	Start()
}

Aggregator defines an interface used to aggregate operation throughput.

type Factory

type Factory interface {
	// Initialize performs internal initialization of the factory.
	Initialize(metricsFactory metrics.Factory, ssFactory storage.SamplingStoreFactory, logger *zap.Logger) error

	// CreateStrategyStore initializes the StrategyStore and returns it.
	CreateStrategyStore() (StrategyStore, Aggregator, error)
}

Factory defines an interface for a factory that can create implementations of different strategy storage components. Implementations are also encouraged to implement plugin.Configurable interface.

type StrategyStore

type StrategyStore interface {
	// GetSamplingStrategy retrieves the sampling strategy for the specified service.
	GetSamplingStrategy(ctx context.Context, serviceName string) (*api_v2.SamplingStrategyResponse, error)
}

StrategyStore keeps track of service specific sampling strategies.
