Christian Haudum	d8cc1cea83	chore: Make dedicated iterator package (#13273) ... Iterators of various types are widely used throughout the Loki code base. With the recent code additions of the bloom filters, a new set of utility functions for iterators emerged in `github.com/grafana/loki/v3/pkg/storage/bloom/v1`. The package defines interfaces for various common types, but also provides implementations to create and compose new iterators that implement these interfaces. This new package uses Go Generics. - However, at the current state, there are multiple iterator interfaces and implementations, which adds cognitive overhead in understanding how they work and which ones should be used. The idea is to unify them into a single iterator lib for Loki. - As a first step towards a single iterator library for the Loki code base, this PR moves the utilities from the `pkg/storage/bloom/v1` package to the `pkg/iter/v2` package. - Second, it changes the existing `EntryIterator` and `SampleIterator` iterators to "inherit" `v2.CloseIterator` in order to expose the same function names. - And lastly, naming conventions of iterator interfaces and structs are unified. The basic iterator interface (defined in `pkg/iter/v2/interface.go`) looks like so: ```go // Usage: // // for it.Next() { // curr := it.At() // // do something // } // if it.Err() != nil { // // do something // } type Iterator[T any] interface { Next() bool Err() error At() T } ``` --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago

Salva Corts	52a3f16039	Flag categorize labels on streams response (#10419) ... We recently introduced support for ingesting and querying structured metadata in Loki. This adds a new dimension to Loki's labels since now we arguably have three categories of labels: _stream_, _structured metadata_, and _parsed_ labels. Depending on the origin of the labels, they should be used in LogQL expressions differently to achieve optimal performance. _stream_ labels should be added to stream matchers, _structured metadata_ labels should be used in a filter expression before any parsing expression, and _parsed_ labels should be placed after the parser expression extracting them. The Grafana UI has a hard time dealing with this same problem. Before https://github.com/grafana/grafana/pull/73955, the filtering functionality in Grafana was broken since it was not able to distinguish between _stream_ and _structured metadata_ labels. Also, as soon as a parser expression was added to the query, filters added by Grafana would be appended to the end of the query regardless of the label category. The PR above implements a workaround for this problem but needs a better API on Loki's end to mitigate all corner cases. Loki currently returns the following JSON for log queries: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "info", "traceID": "68810cf0c94bfcca" }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n" ], ... }, { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "debug", "traceID": "a7116cj54c4bjz8s" }, "values": [ [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n" ], ... }, ... ``` As can be seen, there is no way we can distinguish the category of each label. This PR introduces a new flag `X-Loki-Response-Encoding-Flags: categorize-labels` that makes Loki return categorized labels as follows: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n", { "structuredMetadata": { "traceID": "68810cf0c94bfcca" }, "parsed": { "level": "info" } } ], [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n", { "structuredMetadata": { "traceID": "a7116cj54c4bjz8s" }, "parsed": { "level": "debug" } } ], ... }, ... ``` Note that this PR only supports log queries, not metric queries. From a UX perspective, being able to categorize labels in metric queries doesn't have any benefit yet. Having said that, supporting this for metric queries would require some minor refactoring on top of what has been implemented here. If we decide to do that, I think we should do it on a separate PR to avoid making this PR even larger. I also decided to leave out support for Tail queries to avoid making this PR even larger. Once this one gets merged, we can work to support tailing. --- **Note to reviewers** This PR is huge since we need to forward categorized all over the codebase (from parsing logs all the way to marshaling), fortunately, many of the changes come from updating tests and refactoring iterators. Tested out in a dev cell with query `'{stream="stdout"} | label_format new="text"`. - Without the new flag: ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED { "data": { "result": [ { "stream": { "new": "text", "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n" ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n" ], ... ``` - With the new flag ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED X-Loki-Response-Encoding-Flags:categorize-labels { "data": { "encodingFlags": [ "categorize-labels" ], "result": [ { "stream": { "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n", { "parsed": { "new": "text" } } ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n", { "parsed": { "new": "text" } } ], ... ```	2 years ago
Owen Diehl	c405db4317	Format + Library for building bloom filter "blocks" from chunks (#10780) ... This PR introduces both a binary format for bloom filter "blocks" and a library for building/querying them. Each "block" consists of two files: 1) `Index`. This is a list of individually compressed pages of stream+chunk information sorted in ascending fingerprint order. Each series lists both the chunks indexed in the bloom filters as well as the relevant offsets for said series in the bloom file. 2) `Blooms`. This is a list of individually compressed pages of bloom filters for each series, again sorted in ascending fingerprint order. There is still more work to do, but I'm opening this PR as an initial pass.	2 years ago

Kaviraj Kanagaraj	bbfb13c3e4	Pin `chunk` and `index` format to `schema` version. (#10213) ... We pin all three `Chunk`, `HeadBlock` and `TSDB` Version to `schema` version in period config. This is the following mapping (after being discussed with @owen-d and @sandeepsukhani ) `v12` (current existing schema) - ChunkFormatV3 (UnorderedHeadBlock) + TSDBv2 `v13` (introducing new schema) - ChunkFormatV4 (UnorderedWithNonIndexedLabelsHeadBlockFmt) + TSDBv3 Note the new schema `v13` supports the latest chunk and index format. **NOTES for Reviewer** 1. General approach is we removed the idea of `index.LiveFormat`, `chunkenc.DefaultChunkFormat` and `chunkenc.DefaultHeadBlockFmt` and made following two changes. These variables were used before to tie chunk and tsdb formats specific to Loki versions. This PR remove that coupling and pin these formats to `schema` version instead. 1. These variables were replaced with explicit chunk and index formats within those packages (and it's tests) 2. If these variables were used outside it's own packages say by ingester, compactor, etc. Then we extract correct chunk and index versions from the `schema` config. 2. Add two methods to `periodConfig`. (1) `ChunkFormat()` returning chunk and head format tied to schema (2) `TSDBFormat()` returning tsdb format tied to schema. 2. Other ideas I thought of doing but didn't end up doing is make `ChunkFormat` and `IndexFormat` as separate type (rather than `byte` and `int` currently. Similar to `HeadBlockFmt` type). But didnt' do it eventually to keep the PR small and don't want to complicate with lots of changes. 4. Moved couple of test cases from `chunkenc` to `config` package, because the test case was actually testing methods on `schemaconfig` and it was creating cycling dependencies. --------- Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com>	2 years ago

This causes a mismatch in chunk and head block format which ideally should be on the same version. The problem happens when we rollback from v4 chunk and block format to v3 and the head is empty in checkpoint which then [gets set to the default version](ce91076dd4/pkg/ingester/checkpoint.go (L106)) i.e v3 while the checkpointed chunk would be v4. **Checklist** - [x] Tests updated --------- Co-authored-by: Salva Corts <salva.corts@grafana.com>	2 years ago
Salva Corts	2754176239	Fixes for non-indexed metadata (#10167) ... **What this PR does / why we need it**: This PR fixes a bug while recovering from the WAL. Before this PR, when reading a head from the WAL, we'd attempt to create a chunk with the head fmt of the WAL head. If we change the chunk fmt to v4, we'd fail to rebound chunks since v4 may be incompatible with the head fmt from the WAL.

This PR optimizes resource usage for storing and processing non-indexed labels by doing string interning. We will store deduped label names and values as a list in chunks in the newly added non-indexed labels section. The labels would then be referenced in blocks by their index(called symbols). Additionally, I have started the convention of writing lengths of sections with their offsets within chunks, making it easier to introduce new sections. The section offsets and lengths would be stored at the end of the chunk, similar to [TOC](https://ganeshvernekar.com/blog/prometheus-tsdb-persistent-block-and-its-index/#a-toc) in TSDB. **Checklist** - [x] Tests updated	3 years ago

Owen Diehl	2836c79537	Revert "Loki: Fix memchunk headblock filter" (#8594) ... Reverts grafana/loki#8591 This altered an internal API. We execute queries that are inclusive of start and exclusive of end: `[start,end)` and shouldn't break this. We use other ways to ensure `start==end` still works, such as by using the lookback-period to alter the range of queries: https://github.com/grafana/loki/blob/main/pkg/logql/evaluator.go#L179-L181	3 years ago

Before: `4724260 maxresident KB`; after: `375804 maxresident KB` ### BenchmarkRead Replace reporting of MB/s which gave several values for each encoding as Go hunted for the right number of benchmark iterations. Add stats to the context for decoding, otherwise a new stats object is created each time round the loop. Re-order so all unsampled results come before all sampled results.

Bryan Boreham	9498ea2c02	chunks: decode varints directly from byte buffer; stop panicing on some corrupt inputs (#7264) ... **What this PR does / why we need it**: This is much faster, since we don't pay for byte-at-a-time reads from the buffer. For best performance with gzip and lz4, we still want a bufio.Reader. We don't need the pool of buffered readers now. Other compression formats have their own internal buffers so don't need extra buffering. **Checklist** - [x] Reviewed the `CONTRIBUTING.md` guide - NA Documentation added - NA Tests updated - [x]
