Karsten Jeschkies	b35bbd80d6	Support content negotiation between query frontend and querier. (#9813) ... **What this PR does / why we need it**: Currently, the querier sends results to the query frontend in JSON which is then decoded to Protobuf. It is more efficient to send the results as Protobuf. This will also allow to extend the results with custom data structures. The change is backwards compatible through content negotiation. **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] Tests updated - [x] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

Travis Patterson	db97058a84	Series volume endpoint (#9704) ... This changes the `label_volume` endpoint to the `series_volume` endpoint. The new endpoint still returns volumes but now it does it for the requested streams defined by the selector names passed rather than individual labels. All relevant non-requested labels are aggregated into the returned results ex: Assume we have the following streams: ``` {cluster="prod", team="A", component="foo"} {cluster="prod", team="B", component="foo"} {cluster="dev", team="A", component="foo"} {cluster="dev", team="B", component="foo"} ``` - requesting `{cluster="prod"}` returns one result for all streams containing `{cluster="prod"}` - requesting `{cluster=~".+"}` returns two results for the streams containing `{cluster="prod"}` and `{cluster="dev"}` - requesting `{cluster=~".+", team=".+"}` returns four results for the streams containing: ``` {cluster="prod", team="A"} {cluster="prod", team="B"} {cluster="dev", team="A"} {cluster="dev", team="B"} ``` --------- Co-authored-by: Trevor Whitney <trevorjwhitney@gmail.com>	3 years ago
Travis Patterson	065bee7e72	Label Volume Endpoint (#9588) ... For a given set of matchers, returns the top N associated label/value pairs by volume. A query for `{cluster=prod}` will return ``` cluster=prod: size (total logs matching this matcher) . . . nth-label=nth-value ``` This is to service use cases where users want to understand where their log volume has come from by label without making multiple requests to the stats endpoint. Note: This PR is a monster but it's mostly plumbing. I've pointed out the most interesting bits that actually get the volumes from ingesters/indexs	3 years ago
