示例1: addToIndexFromKey

// addToIndexFromKey will pull the measurement name, series key, and field name from a composite key and add it to the
// database index and measurement fields
func (e *Engine) addToIndexFromKey(shardID uint64, key []byte, fieldType influxql.DataType, index *tsdb.DatabaseIndex) error {
	seriesKey, field := SeriesAndFieldFromCompositeKey(key)
	measurement := tsdb.MeasurementFromSeriesKey(string(seriesKey))

	m := index.CreateMeasurementIndexIfNotExists(measurement)
	m.SetFieldName(field)

	mf := e.measurementFields[measurement]
	if mf == nil {
		mf = tsdb.NewMeasurementFields()
		e.measurementFields[measurement] = mf
	}

	if err := mf.CreateFieldIfNotExists(field, fieldType, false); err != nil {
		return err
	}

	// Have we already indexed this series?
	ss := index.SeriesBytes(seriesKey)
	if ss != nil {
		// Add this shard to the existing series
		ss.AssignShard(shardID)
		return nil
	}

	// ignore error because ParseKey returns "missing fields" and we don't have
	// fields (in line protocol format) in the series key
	_, tags, _ := models.ParseKey(seriesKey)

	s := tsdb.NewSeries(string(seriesKey), tags)
	index.CreateSeriesIndexIfNotExists(measurement, s)
	s.AssignShard(shardID)

	return nil
}
