Travis Patterson	7f42137584	Use Line Filters in StringLabelFilter (#8659) ... We've done a ton of work to optimize regexes in line filters but nothing in label filters. To avoid duplicating the work or reworking all of our filter types, this PR creates a new label filter that has an optimized line filter. It uses that against the label value to determine if they match. Note on Benchmarks: the input string for this is 1114195 bytes long. The `not` test tells us that our approach is quite a lot slower when the literal pattern isn't present in the input. The size of the input really emphasizes it.

For example, if the overwhelming majority of chunks are small we may decide to cache only small chunks to decrease the number of requests to the object store; we could fit more chunks in cache this way, which may have a positive performance impact.	2 years ago

Bayan Taani	68a9fd6c0a	Add logfmt selective label extraction (#6675) ... <!-- Thanks for sending a pull request! Before submitting: 1. Read our CONTRIBUTING.md guide 2. Name your PR as `<Feature Area>: Describe your change`. a. Do not end the title with punctuation. It will be added in the changelog. b. Start with an imperative verb. Example: Fix the latency between System A and System B. c. Use sentence case, not title case. d. Use a complete phrase or sentence. The PR title will appear in a changelog, so help other people understand what your change will be. 3. Rebase your PR if it gets out of sync with main --> **What this PR does / why we need it**: This PR introduces extracting labels from a log line in `logfmt`, with an extra option to rename them. For example, this query: ``` {app=”foo”} | logfmt msg,status ``` will extract the labels `msg` and `status` from the following logfmt line: ``` level=error ts=2021-02-12T19:18:10.037940878Z caller=client.go:294 component=client host=observability-loki-gateway msg="final error sending batch" status=400 error="server returned HTTP status 400 Bad Request (400): entry with timestamp 2021-02-12 19:18:08.917452 +0000 UTC ignored, reason: 'entry out of order' for stream..." ``` With the following results: ``` msg="final error sending batch" status=”400” ``` -------------- Another possible scenario with label renaming: ``` {app=”foo”} | logfmt message="msg", status ``` That produces the following results: ``` message="final error sending batch" status=”400” ``` **Which issue(s) this PR fixes**: Fixes #3355 **Special notes for your reviewer**: <!-- Note about CHANGELOG entries, if a change adds: * an important feature * fixes an issue present in a previous release, * causes a change in operation that would be useful for an operator of Loki to know then please add a CHANGELOG entry.

Travis Patterson	eb1b72ab80	Fix ruler deadlock (#8486) ... A circular dependency between the Prometheus rules.Manager and the MemStore causes occasional deadlock in the rulers. This change makes both the manager and the memstore rely on the `GroupLoader` interface to break the circular dependency. The manger holding the `GroupLoader` only ever adds rules to it so we add another layer to cleanup any leftover state after an update happens.
