Christian Haudum	ce71f1cf95	feat(api)!: Fail log queries when executed on instant query endpoint (#13421 ) ### What this PR does / why we need it Background A log selector expression is a LogQL expression that returns logs, in contrast to a sample expressions, which returns metrics (samples). The simplest form of log selector expressions are label matchers, e.g. `{env="prod"}`. Change This PR changes the behaviour of Loki so that the instant query endpoint `/api/v1/query` does not allow sending a log selector expression as query any more. Instead, it returns a status code 400 (Bad Request) with the error message "log queries are not supported as an instant query type, please change you query to a range query type". Why Previously this API endpoint allowed these types of log queries, but returned inconsistent results, which where a major cause for confusion. Returning a concise error helps the user understand that they likely selected the wrong query type in Grafana when executing the query. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	11 months ago

Christian Haudum	fc264310ce	perf: Introduce fixed size memory pool for bloom querier (#13039 ) This PR introduces a fixed size memory pool for bloom pages that are loaded in the block querier. The aim of a fixed size pool of `[]byte` buffers is to reduce the amount of allocations, as well as to control the maximum heap size to prevent OOMing of the bloom gateways. Also, with the current usage of a `sync.Pool`, the query parallelism (`bloom-gateway.worker-concurrency` and `bloom-gateway.block-query-concurrency`) was defined by the `bloom.max-query-page-size` (and vice versa), because the max page size could be loaded `workers * concurrency` times at the same time. Most of the time, though, smaller pages are loaded, and therefore concurrency is not optimized. With the new fixed size memory pool, this problem should be solved. The pool is divided into slabs of different sizes holding different amounts of buffers; a larger amount of small sized buffers and a smaller amount of large sized buffers.

Danny Kopping	bcd03150c9	Query-frontend: customisable query splitting for queries overlapping `query_ingester_within` window (#11535 ) What this PR does / why we need it: The config option `query_ingesters_within` defines the window during which logs _could_ be present on ingesters, and as such queriers will send queries to ingesters instead. `split_queries_by_interval` is defined to split queries into subqueries for increased parallelism. Aggressive query splitting within the `query_ingesters_within` window can result in overloading ingesters with unnecessarily large numbers of subqueries, which perversely can impact writes. `query_ingesters_within` is set to 3h by default. In Grafana Cloud Logs we set `split_queries_by_interval` as low as 15m (defaults to 1h), which would result in result in 3*60/15=12 requests. Every querier queries every ingester during this window, so that's 12 requests _per ingester per query_ which has the `query_ingesters_within` window in its time range _(i.e. a query from now to now-7d would include the `query_ingesters_within` window as well, now-3h to now-7d would not)_. However, we _do_ want to split queries so an ingester won't have to handle a query for a full `query_ingesters_within` window - this could involve a large amount of data. To account for this, this PR introduces a new option `split_ingester_queries_by_interval` on the query-frontend; this setting is disabled by default. ![image](https://github.com/grafana/loki/assets/373762/2e671bd8-9e8d-4bf3-addf-bebcfc25e8d7)	1 year ago

Karsten Jeschkies	9aae25008d	Optimize series response format by using repeated fileds. (#11498 ) What this PR does / why we need it: The Protobuf map type is encodied as a repeated field of map entries. Decoding them to a slice is much faster than decoding them into a map. Since Loki is not using the fast key check for a map we can use the slice decoding. This change also allows us to decode the JSON directly into the right protobuf struct. This doulbes the JSON decoding speed and reduces the memory pressure by ~40%. ``` › go test -bench=. -run=^$ -count=10 ./pkg/querier/queryrange > before.log › go test -bench=. -run=^$ -count=10 ./pkg/querier/queryrange > after.log › benchstat before.log after.log goos: darwin goarch: arm64 pkg: github.com/grafana/loki/pkg/querier/queryrange │ before.log │ after.log │ │ sec/op │ sec/op vs base │ ResponseMerge/mergeStreams_unlimited-10 32.36m ± 0% 32.63m ± 2% ~ (p=0.393 n=10) ResponseMerge/mergeOrderedNonOverlappingStreams_unlimited-10 1.050m ± 1% 1.080m ± 3% +2.84% (p=0.005 n=10) ResponseMerge/mergeStreams_limited-10 33.02m ± 0% 32.60m ± 1% -1.29% (p=0.004 n=10) ResponseMerge/mergeOrderedNonOverlappingStreams_limited-10 15.11m ± 0% 15.07m ± 0% ~ (p=0.075 n=10) _CodecDecodeLogs-10 4.395m ± 1% 4.364m ± 0% -0.72% (p=0.005 n=10) _CodecDecodeSamples-10 16.97m ± 0% 16.84m ± 2% -0.77% (p=0.023 n=10) _CodecDecodeSeries/application/vnd.google.protobuf-10 745.8µ ± 8% 736.8µ ± 12% ~ (p=0.739 n=10) _CodecDecodeSeries/application/json;_charset=utf-8-10 15.37m ± 1% 10.60m ± 0% -31.03% (p=0.000 n=10) _MergeResponses-10 1186.9m ± 2% 149.8m ± 1% -87.38% (p=0.000 n=10) _UnwrapSeries-10 9.399m ± 1% 4.049m ± 0% -56.92% (p=0.000 n=10) _DecodeMergeEncodeCycle-10 666.0m ± 3% 194.6m ± 0% -70.79% (p=0.000 n=10) geomean 18.87m 12.51m -33.70% │ before.log │ after.log │ │ B/op │ B/op vs base │ _CodecDecodeLogs-10 3.649Mi ± 0% 3.649Mi ± 0% ~ (p=0.364 n=10) _CodecDecodeSamples-10 18.12Mi ± 0% 18.12Mi ± 0% ~ (p=0.926 n=10) _CodecDecodeSeries/application/vnd.google.protobuf-10 7.647Mi ± 0% 7.647Mi ± 0% ~ (p=0.587 n=10) _CodecDecodeSeries/application/json;_charset=utf-8-10 27.94Mi ± 0% 16.99Mi ± 0% -39.18% (p=0.000 n=10) _MergeResponses-10 2.362Mi ± 0% 2.408Mi ± 0% +1.98% (p=0.000 n=10) _UnwrapSeries-10 19.495Mi ± 0% 8.595Mi ± 0% -55.91% (p=0.000 n=10) _DecodeMergeEncodeCycle-10 772.3Mi ± 0% 772.3Mi ± 0% ~ (p=0.912 n=10) geomean 17.50Mi 14.54Mi -16.91% │ before.log │ after.log │ │ allocs/op │ allocs/op vs base │ _CodecDecodeLogs-10 41.10k ± 0% 41.10k ± 0% ~ (p=1.000 n=10) ¹ _CodecDecodeSamples-10 411.9k ± 0% 411.9k ± 0% ~ (p=1.000 n=10) _CodecDecodeSeries/application/vnd.google.protobuf-10 32.00 ± 0% 32.00 ± 0% ~ (p=1.000 n=10) ¹ _CodecDecodeSeries/application/json;_charset=utf-8-10 304.2k ± 0% 298.1k ± 0% -2.01% (p=0.000 n=10) _MergeResponses-10 100.1k ± 0% 100.1k ± 0% -0.00% (p=0.002 n=10) _UnwrapSeries-10 201.1k ± 0% 198.0k ± 0% -1.54% (p=0.000 n=10) _DecodeMergeEncodeCycle-10 203.1k ± 0% 203.1k ± 0% ~ (p=0.621 n=10) geomean 48.95k 48.70k -0.51% ¹ all samples are equal ``` Checklist - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (required) - [ ] Documentation added - [x] Tests updated - [ ] `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`.

Salva Corts	4248825ad2	Bloom-compactor Sharding (#11154 ) What this PR does / why we need it: This PR adds tenant and fingerprint (FP) sharding to bloom compactors. Note that the bloom-compactor doesn't yet perform any compaction, but iterates through all tables, tenants, and series checking if the compactor owns the tenant and the series (by the series FP). Actual compaction will be implemented with https://github.com/grafana/loki/pull/11115. A new structure `Job` is added which will carry around all the context for a compaction job such as the tenant ID, the table name, and the series FP. The sharding strategy has two methods: - `OwnsTenant(tenant string)`: Checks if the compactor shard owns the tenant. - `OwnsJob(job Job)`: Checks (again) if the compactor owns the job's tenant. Then, it checks if the compactor owns the job's fingerprint by looking inside the tenant subring. We add a new per-tenant limit: `bloom_compactor_shard_size`. If it's 0, the tenant can use all compactors (i.e. `OwnsTenant` will always return `true`), otherwise, only `bloom_compactor_shard_size` out of the total number of compactors will own the tenant. A given job's FP will be owned by exactly one compactor within the tenant shard. Special notes for your reviewer: - Added a bunch of metrics in `metrics.go` - Added a test for the sharding strategy	2 years ago
