Christian Haudum	863acc0152	chore(blooms): Make block query concurrency configurable (#12292 ) A concurrency of 10 per worker seems to be too high for a reasonable 8GiB memory limit on bloom gateways. So this PR makes the concurrency configurable and uses a default of 4. Memory usage of loading block pages into memory therefore being: ``` worker_concurrency x block_query_concurrency x max_block_page_size x 2 ``` With current defaults: ``` 4 x 4 x 32MiB x 2 = 1GiB ``` Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	1 year ago

Paul Rogers	472496feb7	Parse JSON String arrays properly so string elements can be retrieved (#11921 ) What this PR does / why we need it: This PR imports the newly forked grafana/jsonparser over the buger/jsonparser module. The latter has seemingly been abandoned. PR 10690 introduces a fix to the jsonparser module, which has been incorporated into the grafana fork of the module. The PR is designed to fix accessing string array elements from within a JSON structure. For example, with the following JSON: `{"log":{"message":{"content":{"misses":["a","b","c","d"]}}}}` The Loki code, before this PR, when searching for `json misses = "log.message.content.misses[0]" ` will result in an "Unknown value type error". After this PR is merged, the result will assign `a` to the `misses` variable.

Travis Patterson	2c9482d8a2	reset the basemap when the labelsbuilder is reset (#11771 ) This PR fixes an issue where the `label_format` stage sometimes doesn't populate labels when it should. The label `baz` exists on all log lines but is only populated on the first line. ![image](https://github.com/grafana/loki/assets/1413241/86585a94-937f-4e07-9657-b94699ce8586) The issue is this call to [IntoMap](`06bb20914b/pkg/logql/log/fmt.go (L403)`). It tries to avoid copying the map multiple times [here](`06bb20914b/pkg/logql/log/labels.go (L482)`) but the `baseMap` variable isn't reset when the labels builder is reset. As a result, calls to to `IntoMap` after the builder has been reset mean that `!b.hasDel() && !b.hasAdd() && !b.HasErr()` evaluates to `true` but `b.baseMap == nil` also evaluates to `true` so no items are copied. This PR makes it so that `b.baseMap` is reset along with the rest of the builder's state in `Reset`	1 year ago
Poyzan	6d66ea382c	[Fix] OR statements not being evaluated as part of nested line filters (#11735 ) What this PR does / why we need it: When nester line filters were being evaluated, the `OR` statements in right expressions were omitted and only `LineFilters` were returned. Resulting in only first value being returned. It can be reproduced in stringer unit test failing with, ``` Error Trace: /Users/poyzannur/workspace/loki/pkg/logql/syntax/ast_test.go:535 Error: Not equal: expected: "{app=\"foo\"} \|= \"foo\" or \"bar\" \|= \"baz\" or \"bal\"" actual : "{app=\"foo\"} \|= \"foo\" or \"bar\" \|= \"baz\"" ``` We now return the `OR` expression as part of nested line filters.

Ed Welch	e21b525674	Loki: increase the limit for query length from 5k to 128k (#11701 ) What this PR does / why we need it: We originally added this limit from fuzz testing and realizing there should be some maximum limit to an allowed query size. The original limit was 5120 based on some internet searching and a best estimate of what a reasonable limit would be. We have seen use cases with queries containing a lot of filter expressions or long expanded variable names where this limit was too small. Apparently the spec does not specify a limit, and more internet searching suggests almost all browsers will handle 100k+ length urls without issue Some limit here still seems prudent however, so the new limit is now 128k.

Travis Patterson	3373cc54f6	fix: use syntax.MustClone to avoid panics when cloning expressions (#11595 ) The clone function in rangemapper has been a persistent source of panics due to the way stringifying exprs changed the way the original query was represented. This PR replaces the `clone` function with `syntax.MustClone`. It clones the expression by actually walking the AST rather than doing `expr -> string -> parse`. It might still panic but for a more fundamental reason than because of issues with the string representation.	1 year ago

Kaviraj Kanagaraj	ce574485cf	feat(caching): Support caching `/series` and `/labels` query results (#11539 ) What this PR does / why we need it: Add support for caching metadata queries (both series and labels). caching happens after splitting similar to other types of queries. This pr adds the following configs to enable them. ``` cache_series_results: true\|false (default false) cache_label_results: true\|false (default false) ``` And the cache backend for them can be configured using `series_results_cache` and `label_results_cache` blocks under the `query_range` section. Currently the split interval for metadata queries is fixed and defaults to 24h, this pr makes it configurable by introducing `split_metadata_queries_by_interval` Which issue(s) this PR fixes: Fixes #<issue number> 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 - [ ] `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`.
