Functions

func BuildCustomIterator added in v0.5.0 

func BuildCustomIterator(
	dps [][]Datapoint,
	testTags map[string]string,
	seriesID, seriesNamespace string,
	start time.Time,
	blockSize, stepSize time.Duration,
) (encoding.SeriesIterator, models.Bounds, error)

func BuildTestSeriesIterator 

func BuildTestSeriesIterator() (encoding.SeriesIterator, error)

BuildTestSeriesIterator creates a sample SeriesIterator This series iterator has two identical replicas. Each replica has two blocks. The first block in each replica is merged and has values 1->30 The values 1 and 2 appear before the SeriesIterator start time, and are not expected to appear when reading through the iterator The second block is unmerged; when it was merged, it has values 101 -> 130 from two readers, one with even values and other with odd values Expected data points for reading through the iterator: [3..30,101..130], 58 in total SeriesIterator ID is 'foo', namespace is 'namespace' Tags are "foo": "bar" and "baz": "qux"
