Types

type InvertedIndex

type InvertedIndex struct {
	// contains filtered or unexported fields
}

InvertedIndex implements a in-memory inverter index from label pairs to fingerprints. It is sharded to reduce lock contention on writes.

func New

func New() *InvertedIndex

New returns a new InvertedIndex.

func (*InvertedIndex) Add

func (ii *InvertedIndex) Add(labels []client.LabelAdapter, fp model.Fingerprint) labels.Labels

Add a fingerprint under the specified labels. NOTE: memory for `labels` is unsafe; anything retained beyond the life of this function must be copied

func (*InvertedIndex) Delete

func (ii *InvertedIndex) Delete(labels labels.Labels, fp model.Fingerprint)

Delete a fingerprint with the given label pairs.

func (*InvertedIndex) LabelNames

func (ii *InvertedIndex) LabelNames() []string

LabelNames returns all label names.

func (*InvertedIndex) LabelValues

func (ii *InvertedIndex) LabelValues(name string) []string

LabelValues returns the values for the given label.

func (*InvertedIndex) Lookup

func (ii *InvertedIndex) Lookup(matchers []*labels.Matcher) []model.Fingerprint

Lookup all fingerprints for the provided matchers.
