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. 	2 years ago
Poyzan	599eed7c52	[bloom-compactor] remove BloomCompactorMinTableAge check (#11546) ... **What this PR does / why we need it**: `BloomCompactorMinTableAge` was added with the idea that we will skip most recent index files from ingesters that are not compacted into TSDB indexes yet. The default value is an hour. This blocks bloom-compacter processing TSBD of the day, because end timestamp is always in the last 15 mins. We can either reduce it something lower than the frequency of TSDB indexes being built (< 15mins). Here I choose to remove it altogether, assuming uncompacted indexes from ingesters will not be processed as a table as there won't be a schema for that table with the [check here](https://github.com/grafana/loki/blob/main/pkg/bloomcompactor/bloomcompactor.go#L268-L272).	2 years 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`.

Vladyslav Diachenko	9b691904ef	BloomShipper: add cache for downloaded blocks (#11394) ... adapted embeddedcache.go to store downloaded bloom blocks on local filesystem. **What this PR does / why we need it**: This cache will be used by bloom-gateway to not download the blocks each time. In the cache we store the objects(`cachedBlock` struct) that contain: 1. `blockDirectory`: the `path` to the directory where the block was extracted 2. `activeQueriers`: thread-safe counter of active block users. This field is important because we do not want the directory to be removed while it's in use. 3. rest fields are needed for service needs When the downloadingWorker receives this entity, it increases the counter `activeQueriers` and creates blockQuerier wrapper that has `Close` function that will decrease the counter once blockQuerier is not needed anymore. When the cache entry is being removed from the cache, the cache calls the function `removeDirectoryAsync` which asynchronously removes the block's folder. This function checks every `Xms` if there are still active block queriers and once `activeQueriers` count is `0` the folder will be removed. Also, there is a timeout in this function, and once the timeout is reached, the folder will be force removed. **Special notes for your reviewer**: * If the cache is disabled, then the blocks will be downloaded each time the block is requested. * If the cache is used, the folder will be deleted by embeddedCache when it reaches memory size limit or items count limit. Otherwise, the block's folder will be deleted when `Close` function is called. **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`.

Ashwanth	d9f3bf30b1	config: adds `frontend.max-query-capacity` to tune per-tenant query capacity (#11284) ... **What this PR does / why we need it**: Adds a new config `frontend.max-query-capacity` that allows users to configure what portion of the the available querier replicas can be used by a tenant. `max_query_capacity` is the corresponding YAML option that can be configured in limits or runtime overrides. For example, setting this to 0.5 would allow a tenant to use half of the available queriers. This complements the existing `frontend.max-queriers-per-tenant`. When both are configured, the smaller value of the resulting querier replica count is considered: ``` min(frontend.max-queriers-per-tenant, ceil(querier_replicas * frontend.max-query-capacity)) ``` *All* queriers will handle requests for a tenant if neither limits are applied. **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: noticed that we don't pass down the shuffle sharding limits for frontend (only using it with schedulers) 26f097162a/pkg/loki/modules.go (L895) but the [docs](26f097162a/pkg/validation/limits.go (L276)) mention that`frontend.max-queriers-per-tenant` applies to frontend as well. ``` This option only works with queriers connecting to the query-frontend / query-scheduler, not when using downstream URL. ``` **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] Tests updated - [x] `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	67ecf5007b	Make Blooms-Gateway queue settings configurable (#11321) ... **What this PR does / why we need it**: This PR adds three new settings to the Bloom-Gateway config: - `worker_concurrency`: replaces the `numWorkers` constant. Named after the scheduler's `scheduler_worker_concurrency` config. - `max_outstanding_per_tenant`: replaces the `maxTasksPerTenant` constant. Named after the frontend's `max_outstanding_per_tenant` config. - `pending_tasks_initial_capacity`: replaces the pendingTasksInitialCap constant. **Note to the reviewers:** - I think in the future `max_outstanding_per_tenant` should be configurable per-tenant. This would require refactoring the queue pkg and the frontend/scheduler, so I think it doesn't make sense it in this PR. - I moved the `Limits` struct definition to `config.go` so have all the adjustable settings in the same place.	2 years ago

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

Ashwanth	a118e994d8	Remove shared_store and shared_store_key_prefix from shipper and compactor (#10840) ... **What this PR does / why we need it**: #### Removes `shared_store` and `shared_store_key_prefix` from index shipper and compactor configs and their corresponding CLI flags. - `-tsdb.shipper.shared-store` - `-boltdb.shipper.shared-store` - `-tsdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.compactor.shared-store` - `-boltdb.shipper.compactor.shared-store.key-prefix` `shared_store` has been a confusing option allowing users to easily misconfigure Loki. Going forward `object_store` setting in the [period_config](https://grafana.com/docs/loki/latest/configure/#period_config) (which already configured the store for chunks) will be used to configure store for the index. And the newly added `path_prefix` option under the `index` key in `period_config` will configure the path under which index tables are stored. This change enforces chunks and index files for a given period reside together in the same storage bucket. More details in the upgrade guide. --- `-compactor.delete-request-store` has to be **explicitly configured** going forward. Without setting this, loki wouldn't know which object store to use for storing delete requests. Path prefix for storing deletes is decided by `-compactor.delete-request-store.key-prefix` which defaults to `index/`. **Checklist** - [X] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [X] Documentation added - [X] Tests updated - [x] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [X] 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`.
