Types

type AsyncStore

type AsyncStore struct {
	Store
	// contains filtered or unexported fields
}

AsyncStore does querying to both ingesters and chunk store and combines the results after deduping them. This should be used when using an async store like boltdb-shipper. AsyncStore is meant to be used only in queriers or any other service other than ingesters. It should never be used in ingesters otherwise it would start spiraling around doing queries over and over again to other ingesters.

}

Config chooses which storage client to use.

func (*Config) RegisterFlags

func (cfg *Config) RegisterFlags(f *flag.FlagSet)

RegisterFlags adds the flags required to configure this flag set.

func (*Config) Validate

func (cfg *Config) Validate() error

Validate config and returns error on failure

type IngesterQuerier

type IngesterQuerier interface {
	GetChunkIDs(ctx context.Context, from, through model.Time, matchers ...*labels.Matcher) ([]string, error)
	Stats(ctx context.Context, userID string, from, through model.Time, matchers ...*labels.Matcher) (*stats.Stats, error)
	LabelVolume(ctx context.Context, userID string, from, through model.Time, limit int32, matchers ...*labels.Matcher) (*logproto.LabelVolumeResponse, error)
}

type LazyChunk

type LazyChunk struct {
	Chunk   chunk.Chunk
	IsValid bool
	Fetcher *fetcher.Fetcher
	// contains filtered or unexported fields
}

LazyChunk loads the chunk when it is accessed.

func (*LazyChunk) IsOverlapping

func (c *LazyChunk) IsOverlapping(with *LazyChunk, direction logproto.Direction) bool

func (*LazyChunk) Iterator

func (c *LazyChunk) Iterator(
	ctx context.Context,
	from, through time.Time,
	direction logproto.Direction,
	pipeline log.StreamPipeline,
	nextChunk *LazyChunk,
) (iter.EntryIterator, error)

Iterator returns an entry iterator. The iterator returned will cache overlapping block's entries with the next chunk if passed. This way when we re-use them for ordering across batches we don't re-decompress the data again.

func (*LazyChunk) SampleIterator

func (c *LazyChunk) SampleIterator(
	ctx context.Context,
	from, through time.Time,
	extractor log.StreamSampleExtractor,
	nextChunk *LazyChunk,

SampleIterator returns an sample iterator. The iterator returned will cache overlapping block's entries with the next chunk if passed. This way when we re-use them for ordering across batches we don't re-decompress the data again.
