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`.

Owen Diehl	2bd9c91564	Bugfix include cache generations on querier response (#7300) ... We check the cache number (incremented by deletes) after executing a query with the value returned by the queriers which executed it. If they’re different, we know we can’t safely cache. However, we’re never actually returning a number from the queriers. This means that as soon as this cache number is incremented by a delete, it’ll disable the results cache for that tenant completely. I suspect this has been a latent bug since we forked cortex (goes back to missing some code from this [PR](https://github.com/cortexproject/cortex/pull/2279) into cortex from @sandeepsukhani back in the day!). It just showed itself once we started using deletes.	3 years ago
