BaseGenerator contains settings specific for TimescaleDB
func (*BaseGenerator) GenerateEmptyQuery ¶
func (g *BaseGenerator) GenerateEmptyQuery() query.Query
GenerateEmptyQuery returns an empty query.TDengine.
func (*BaseGenerator) NewIoT ¶
func (g *BaseGenerator) NewIoT(start, end time.Time, scale int) (utils.QueryGenerator, error)
