Dylan Guedes	30fbe38341	Revert "Introduces cache to TSDB postings (#9621)" (#11157) ... This reverts commit 1221658fc5. **What this PR does / why we need it**: We decided to discontinue the postings cache a few releases ago for not finding any evidences that postings was the culprit for the bad igw performance. Plus, we noticed a major issue with it: it doesn't bubble down shards correctly, so every query end up processing every shard.	3 years ago
Ashwanth	91cae03fe1	chore: restructure compactor package (#10775) ... **What this PR does / why we need it**: This pr moves the compactor pkg from `pkg/storage/stores/shipper/indexshipper/compactor` to `pkg/compactor` - same level as other high level components (querier, distributor...) table compaction code however resides in the respective store pkg closer to other store specific code. `pkg/storage/stores/shipper/indexshipper/boltdb/compactor/table_compactor.go` `pkg/storage/stores/shipper/indexshipper/tsdb/compactor.go` **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] 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`.

Christian Haudum	2e775f3f44	chore(storage): Restructure shipper packages (#10729) ... **What this PR does / why we need it**: This PR restructures the code for the shipper component of the Loki storage layer. New package layout: ```console $ tree -d pkg/storage/stores/shipper pkg/storage/stores/shipper └── indexshipper ├── boltdb │   └── compactor ├── compactor │   ├── client │   │   └── grpc │   ├── deletion │   ├── deletionmode │   ├── generationnumber │   └── retention ├── downloads ├── gatewayclient ├── index ├── indexgateway ├── storage ├── testutil ├── tsdb │   ├── index │   ├── testdata │   └── testutil ├── uploads └── util 23 directories ``` * TSDB and BoltDB specific code is under `./pkg/storage/stores/shipper/indexshipper/tsdb` and `./pkg/storage/stores/shipper/indexshipper/boltdb` respectively. * Common code for both TSDB and BoltDB is directly under `./pkg/storage/stores/shipper/indexshipper` and subdirectories, such as `uploads/`, `downloads/`, `compactor/`, ... **Special notes for your reviewer**: This PR is identical to https://github.com/grafana/loki/pull/10724 except of the package `pkg/storage/stores/indexshipper` the package is `pkg/storage/stores/shipper/indexshipper` (one level deeper).

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>	3 years ago
Dylan Guedes	1221658fc5	Introduces cache to TSDB postings (#9621) ... **What this PR does / why we need it**: Introduces a new interface for fetching TSDB postings and implements a cached TSDB postings. The new postings interface is named `PostingsReader` and contains two implementations: a simple one, which is identical to the former Postings behavior, and a new one, that caches postings using the existing `index_queries_cache_config`. By default, the simple/former implementation is used. The new cached implementation can be configured in the following way: ```yaml storage_config: tsdb_shipper: cache_postings: true ``` In the future, we'll remove the `cache_postings` flag and change the behavior to cache postings by default.	3 years ago
