Christian Haudum	58c8c61905	perf(blooms): Use jumpmap for client side sharding of the filter requests (#12470 ) What this PR does / why we need it: Use the same client-side sharding mechanism for bloom gateway filter requests that we use for client side sharding in the memcached client. This uses DNS discovery to resolve a list of addresses uses as buckets for the jumphash algorithm to shard GroupedChunkRefs across bloom gateway servers. The ring component is still part of the bloom gateway, but it is not used any more.

Christian Haudum	f6cfff5356	refactor(bloomstore): Introduce fetch option for blocks fetcher (#12160 ) Requests to the bloom gateway should not wait for blocks to be downloaded into cache first, but should operate on readily available blocks. This PR introduces fetch options for the bloom store that specify how the store should behave when requesting blocks from block refs. `WithIgnoreMissing`: Ignore errors from blocks that could not be found in object storage, and instead return a `nil` value in the response. `WithFetchAsync`: Return only the blocks that are available locally in cache and dispatch downloading of blocks to the blocks downloader, that operates in the background, and make them available for subsequent requests.

Sandeep Sukhani	e625d7f1ca	otel: add support for per tenant configuration for mapping otlp data to loki format (#11143 ) What this PR does / why we need it: In OTEL, we pick select Resource Attributes to identify the streams and store all the other attributes as Structured Metadata, as explained here. The problem however is that the list of Resource Attributes that are picked as Stream labels are hardcoded, and there is no way to drop unwanted data. This PR adds support for configuring how data is mapped from OTEL to Loki format per tenant. It also adds support for dropping unwanted data. We decided to make the config look similar to Prometheus's relabling config to make it familiar. Special notes for your reviewer: Opening a draft PR to get some initial feedback. I will add documentation in a separate PR. Checklist - [x] Tests updated - [x] `CHANGELOG.md` updated	1 year ago

Ashwanth	51899b521b	feat(metadata cache): adds max_metadata_cache_freshness (#11682 ) What this PR does / why we need it: Adds `max_metadata_cache_freshness` to limit the metadata requests that get cached. When configured, only metadata requests with end time before `now - max_metadata_cache_freshness` are cacheable. _reason for setting the default to 24h?_ metric results cache can [extract samples for the desired time range from an extent](`b6e64e1ef1/pkg/querier/queryrange/queryrangebase/results_cache.go (L78)`) since the samples are associated with a timestamp. But the same is not true for metadata caching, it is not possible to extract a subset of labels/series from a cached extent. As a result, we could return inaccurate results, more that what was requested. for ex: returning results from an entire 1h extent for a 5m query Setting `max_metadata_cache_freshness` to 24h should help us avoid caching recent data. For anything older, we would report cached metadata results at a granularity controlled by `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`.

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. ![image](https://github.com/grafana/loki/assets/373762/2e671bd8-9e8d-4bf3-addf-bebcfc25e8d7)	1 year 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).	1 year ago

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.
