Functions

func AddFlags

func AddFlags(flagSet *flag.FlagSet)

AddFlags from this storage to the CLI

Types

type Configuration

type Configuration struct {
	// MaxTraces is the maximum amount of traces to store in memory.
	// If multi-tenancy is enabled, this limit applies per tenant.
	// Zero value (default) means no limit (Warning: memory usage will be unbounded).
	MaxTraces int `mapstructure:"max_traces"`
}

Configuration describes the options to customize the storage behavior.

func (*Configuration) Validate

func NewFactoryWithConfig(
	cfg Configuration,
	metricsFactory metrics.Factory,
	logger *zap.Logger,
) *Factory

NewFactoryWithConfig is used from jaeger(v2).
