Types

type Buffer 

type Buffer interface {
	Bytes() []byte
}

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

func (DownstreamHandler) Downstreamer 

func (h DownstreamHandler) Downstreamer(ctx context.Context) 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. In the future, it's probably better to replace this with a channel based API so we don't have to do all this ugly edge case handling/accounting
