type MetricNamer

type MetricNamer interface {
	// QueryBuilder used for datasource provider, data source provider call QueryBuilder
	QueryBuilder() querybuilder.QueryBuilder
	// BuildUniqueKey used for predictor now
	BuildUniqueKey() string

	Validate() error

	// Caller means the caller of this MetricNamer, different caller maybe use the same metric
	Caller() string
}

MetricNamer is an interface. it is the bridge between predictor and different data sources and other component such as caller.
