Functions

func NewEmptyResponse 

func NewEmptyResponse(r queryrangebase.Request) (queryrangebase.Response, error)

func NewInstantMetricTripperware 

func NewInstantMetricTripperware(
	cfg Config,
	log log.Logger,
	limits Limits,
	schema config.SchemaConfig,
	codec queryrangebase.Codec,
	metrics *Metrics,
) (queryrangebase.Tripperware, error)

NewInstantMetricTripperware creates a new frontend tripperware responsible for handling metric queries

func NewLabelsTripperware 

func NewLabelsTripperware(
	cfg Config,
	log log.Logger,
	limits Limits,
	codec queryrangebase.Codec,
	metrics *Metrics,
) (queryrangebase.Tripperware, error)

NewLabelsTripperware creates a new frontend tripperware responsible for handling labels requests.

func NewLimitedRoundTripper 

func NewLimitedRoundTripper(next http.RoundTripper, codec queryrangebase.Codec, limits Limits, middlewares ...queryrangebase.Middleware) http.RoundTripper

NewLimitedRoundTripper creates a new roundtripper that enforces MaxQueryParallelism to the `next` roundtripper across `middlewares`.

func NewLimitsMiddleware 

func NewLimitsMiddleware(l Limits) queryrangebase.Middleware

NewLimitsMiddleware creates a new Middleware that enforces query limits.

func NewLogFilterTripperware 

func NewLogFilterTripperware(
	cfg Config,
	log log.Logger,
	limits Limits,
	schema config.SchemaConfig,
	codec queryrangebase.Codec,
	c cache.Cache,
	metrics *Metrics,
) (queryrangebase.Tripperware, error)

NewLogFilterTripperware creates a new frontend tripperware responsible for handling log requests with regex.

func NewLogResultCache 

func NewLogResultCache(logger log.Logger, limits Limits, cache cache.Cache, shouldCache queryrangebase.ShouldCacheFn, metrics *LogResultCacheMetrics) queryrangebase.Middleware

NewLogResultCache creates a new log result cache middleware. Currently it only caches empty filter queries, this is because those are usually easily and freely cacheable. Log hits are difficult to handle because of the limit query parameter and the size of the response. In the future it could be extended to cache non-empty query results. see https://docs.google.com/document/d/1_mACOpxdWZ5K0cIedaja5gzMbv-m0lUVazqZd2O4mEU/edit

func NewSeriesQueryShardMiddleware(
	logger log.Logger,
	confs ShardingConfigs,
	middlewareMetrics *queryrangebase.InstrumentMiddlewareMetrics,
	shardingMetrics *logql.ShardingMetrics,
	limits queryrangebase.Limits,

Types

type Buffer 

type Buffer interface {
	Bytes() []byte
}

type Codec 

type Codec struct{}

func (Codec) DecodeRequest 

func (Codec) DecodeRequest(_ context.Context, r *http.Request, forwardHeaders []string) (queryrangebase.Request, error)

func (Codec) DecodeResponse 

func (Codec) DecodeResponse(ctx context.Context, r *http.Response, req queryrangebase.Request) (queryrangebase.Response, error)

func (Codec) EncodeRequest 

func (Codec) EncodeRequest(ctx context.Context, r queryrangebase.Request) (*http.Request, error)

func (Codec) EncodeResponse 

func (Codec) EncodeResponse(ctx context.Context, res queryrangebase.Response) (*http.Response, error)

func (Codec) MergeResponse 

func (Codec) MergeResponse(responses ...queryrangebase.Response) (queryrangebase.Response, error)

NOTE: When we would start caching response from non-metric queries we would have to consider cache gen headers as well in MergeResponse implementation for Loki codecs same as it is done in Cortex at https://github.com/cortexproject/cortex/blob/21bad57b346c730d684d6d0205efef133422ab28/pkg/querier/queryrange/query_range.go#L170

type DownstreamHandler 

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

func (DownstreamHandler) Downstreamer 

func (h DownstreamHandler) Downstreamer() logql.Downstreamer

Note: After the introduction of the LimitedRoundTripper, bounding concurrency in the downstreamer is mostly redundant The reason we don't remove it is to prevent malicious queries from creating an unreasonably large number of goroutines, such as the case of a query like `a / a / a / a / a ..etc`, which could try to shard each leg, quickly dispatching an unreasonable number of goroutines.

type Limits 

type Limits interface {
	queryrangebase.Limits
	logql.Limits
	QuerySplitDuration(string) time.Duration
	MaxQuerySeries(string) int
	MaxEntriesLimitPerQuery(string) int
	MinShardingLookback(string) time.Duration
}

Limits extends the cortex limits interface with support for per tenant splitby parameters

WithSplitByLimits will construct a Limits with a static split by duration.

type LogResultCacheMetrics 

type LogResultCacheMetrics struct {
	CacheHit  prometheus.Counter
	CacheMiss prometheus.Counter
}

LogResultCacheMetrics is the metrics wrapper used in log result cache.
