Types

type SamplingStore

type SamplingStore struct {
	// contains filtered or unexported fields
}

SamplingStore handles all insertions and queries for sampling data to and from Cassandra

func New

func New(session cassandra.Session, factory metrics.Factory, logger *zap.Logger) *SamplingStore

New creates a new cassandra sampling store.
