Ed Welch	4c88be0ef2	chore: update loki modules for 3.0 release (#12433) ... Signed-off-by: Edward Welch <edward.welch@grafana.com>	2 years ago
Salva Corts	489ac8d529	Extract results cache into new pkg (#11343) ... **What this PR does / why we need it**: This extracts the results cache from `queryrangebase` into its own pkg so we can reuse it in other components such as the bloom-gateway without having to import `queryrangebase`. - Most of the logic inside `pkg/querier/queryrange/queryrangebase/results_cache.go` now lives in `pkg/storage/chunk/cache/results_cache/cache.go`. - Some of the tests in `pkg/querier/queryrange/queryrangebase/results_cache.go` are moved into pkg/storage/chunk/cache/results_cache/cache_test.go. - Note that here we don't have access to the types we use in `queryrangebase` so we created a new set of mock request/response types to test with.	2 years ago
Karsten Jeschkies	05c4b77ed0	Define QueryResponse and QueryRequest protobufs. (#10956) ... **What this PR does / why we need it**: This will be a follow up to https://github.com/grafana/loki/pull/10688 finally switching over to protos. Hang on tight! Everything is behind the feature flag `-frontend.encoding=protobuf` which will disable the transcoding to HTTP and HTTPgRPC. **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] 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/setup/upgrade/_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`.

Karsten Jeschkies	9fcc42dc48	Support protobuf `QueryRequest` in querier. (#10858) ... **What this PR does / why we need it**: This is one step to support pure protobuf encoding without `httpgrpc`.

Salva Corts	fd16425062	Cache index stats requests (#8972) ... **What this PR does / why we need it**: As described in https://github.com/grafana/loki/issues/8973, we are substantially increasing the load of index stat requests we sent to our index gateways. Many of these requests should be easily re-used by caching them. This PR adds caching for index stat requests by reusing the results cache. Here's a demo ([source][1]):  **Which issue(s) this PR fixes**: Fixes https://github.com/grafana/loki/issues/8973 **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [x] Tests updated - [x] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` [1]: https://ops.grafana-ops.net/d/afcaef21-e5ad-49e7-ab06-42a9d7d915eb/index-stats?orgId=1&var-datasource=dev-cortex&var-cluster=dev-eu-west-2&var-namespace=loki-dev-009&var-loki_datasource=Grafana%20Logging&from=1680259907288&to=1680260431814&var-operation=All --------- Co-authored-by: Owen Diehl <ow.diehl@gmail.com>	3 years ago
Danny Kopping	33e44ed39d	Ruler: remote rule evaluation (#8744) ... **What this PR does / why we need it**: Adds the ability to evaluate recording & alerting rules against a given `query-frontend`, allowing these queries to be executed with all the parallelisation & optimisation that regular adhoc queries have. This is important because with `local` evaluation all queries are single-threaded, and rules that evaluate a large range/volume of data may timeout or OOM the `ruler` itself, leading to missed metrics or alerts. When `remote` evaluation mode is enabled, the `ruler` effectively just becomes a gRPC client for the `query-frontend`, which will dramatically improve the reliability of the `ruler` and also drastically reduce its resource requirements. **Which issue(s) this PR fixes**: This PR implements the feature discussed in https://github.com/grafana/loki/pull/8129 (**LID 0002: Remote Rule Evaluation**).	3 years ago

For reference, take a look at PR https://github.com/grafana/loki/pull/5151. * Implement LegacyLabelPair. * Use new Legacy implementations accordingly. * Use LegacySample in compat tests. - Since `compat.go` was forked from Cortex, we can reliably change all mentions from `Sample` to `LegacySample` there.	4 years ago
