Types

type AlignedDatapoints added in v0.15.0 

type AlignedDatapoints []Datapoints

AlignedDatapoints is a list of aligned datapoints.

type Datapoint 

type Datapoint struct {
	Timestamp time.Time
	Value     float64
}

A Datapoint is a single data value reported at a given time.

type Datapoints 

type Datapoints []Datapoint

Datapoints is a list of datapoints.

func (Datapoints) AlignToBounds added in v0.4.6 

func (d Datapoints) AlignToBounds(
	bounds models.Bounds,
	lookbackDuration time.Duration,
	buffer AlignedDatapoints,
) AlignedDatapoints

AlignToBounds returns values aligned to given bounds. To belong to a step, values should be <= stepTime and not stale.

		lookbackDuration time.Duration,
		buffer AlignedDatapoints,
	) AlignedDatapoints

	// AlignToBoundsNoWriteForward returns values aligned to the start time
	// and duration, but does not write points forward after aligning them. This
	// differs from AlignToBounds which will write points forwards if no
	// additional values are found in the values, adding an empty point instead.
	// Takes an optional buffer to allow for memory re-use.
	AlignToBoundsNoWriteForward(
		bounds models.Bounds,
		lookbackDuration time.Duration,
		buffer AlignedDatapoints,
	) AlignedDatapoints
}

Values holds the values for a timeseries. It provides a minimal interface for storing and retrieving values in the series, with Series providing a more convenient interface for applications to build on top of. Values objects are not specific to a given time, allowing them to be pre-allocated, pooled, and re-used across multiple series. There are multiple implementations of Values so that we can optimize storage based on the density of the series.
