Constants for entrypoint names, as exposed in statistics/logging.

Functions ¶

func HitMap ¶

func HitMap(cfg MapConfig) error

HitMap performs load/stress operations according to given config.

Types ¶

type MapBias ¶

type MapBias struct {
	Bias map[MapEntrypointName]int

	// InvalidChance gives the odds of performing an invalid operation, as the N in 1-in-N.
	InvalidChance map[MapEntrypointName]int
	// contains filtered or unexported fields
}

MapBias indicates the bias for selecting different map operations.

func (*MapBias) Choose ¶

func (hb *MapBias) Choose() MapEntrypointName

Choose randomly picks an operation to perform according to the biases.

func (*MapBias) Invalid ¶

func (hb *MapBias) Invalid(ep MapEntrypointName) bool

Invalid randomly chooses whether an operation should be invalid.

type MapConfig ¶

type MapConfig struct {
	MapID         int64
	MetricFactory monitoring.MetricFactory
	Client        trillian.TrillianMapClient
	EPBias        MapBias
	Operations    uint64
	EmitInterval  time.Duration
	IgnoreErrors  bool
}

MapConfig provides configuration for a stress/load test.

type MapEntrypointName ¶

type MapEntrypointName string

MapEntrypointName identifies a Map RPC entrypoint
