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
}示例2: 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(key string, fieldType influxql.DataType, index *tsdb.DatabaseIndex) error {
seriesKey, field := seriesAndFieldFromCompositeKey(key)

if err == nil {
return err
}
s := tsdb.NewSeries(seriesKey, tags)
s.InitializeShards()
index.CreateSeriesIndexIfNotExists(measurement, s)
return nil
}示例3: MeasurementFields
// MeasurementFields returns the measurement fields for a measurement.
func (e *Engine) MeasurementFields(measurement string) *tsdb.MeasurementFields {
e.mu.RLock()
m := e.measurementFields[measurement]
e.mu.RUnlock()
if m != nil {
return m
}
e.mu.Lock()
m = e.measurementFields[measurement]
if m == nil {
m = tsdb.NewMeasurementFields()
e.measurementFields[measurement] = m
}
e.mu.Unlock()
return m
}
