Salva Corts	ee69f2bd37	Split index request in 24h intervals (#8909 ) What this PR does / why we need it: At https://github.com/grafana/loki/pull/8670, we applied a time split of 24h intervals to all index stats requests to enforce the `max_query_bytes_read` and `max_querier_bytes_read` limits. When the limit is surpassed, the following message get's displayed: ![image](https://user-images.githubusercontent.com/8354290/227960400-b74a0397-13ef-4143-a1fc-48d885af55c0.png) As can be seen, the reported bytes read by the query are not the same as those reported by Grafana in the lower right corner of the query editor. This is because: 1. The index stats request for enforcing the limit is split in subqueries of 24h. The other index stats rquest is not time split. 2. When enforcing the limit, we are not displaying the bytes in powers of 2, but powers of 10 ([see here][2]). I.e. 1KB is 1000B vs 1KiB is 1024B. This PR adds the same logic to all index stats requests so we also time split by 24 intervals all requests that hit the Index Stats API endpoint. We also use powers of 2 instead of 10 on the message when enforcing `max_query_bytes_read` and `max_querier_bytes_read`. ![image](https://user-images.githubusercontent.com/8354290/227959491-f57cf7d2-de50-4ee6-8737-faeafb528f99.png) Note that the library we use under the hoot to print the bytes rounds up and down to the nearest integer ([see][3]); that's why we see 16GiB compared to the 15.5GB in the Grafana query editor. Which issue(s) this PR fixes: Fixes https://github.com/grafana/loki/issues/8910 Special notes for your reviewer: - I refactored the`newQuerySizeLimiter` function and the rest of the _Tripperwares_ in `rountrip.go` to reuse the new IndexStatsTripperware. So we configure the split-by-time middleware only once.

Salva Corts	336e08fc4b	Salvacorts/max querier size messaging (#8916 ) What this PR does / why we need it: In https://github.com/grafana/loki/pull/8670 we introduced a new limit `max_querier_bytes_read`. When the limit was surpassed the following error message is printed: ``` query too large to execute on a single querier, either because parallelization is not enabled, the query is unshardable, or a shard query is too big to execute: (query: %s, limit: %s). Consider adding more specific stream selectors or reduce the time range of the query ``` As pointed out in [this comment][1], a user would have a hard time figuring out whether the cause was `parallelization is not enabled`, `the query is unshardable` or `a shard query is too big to execute`. This PR improves the error messaging for the `max_querier_bytes_read` limit to raise a different error for each of the causes above.

Salva Corts	d24fe3e68b	Max bytes read limit (#8670 ) What this PR does / why we need it: This PR implements two new per-tenant limits that are enforced on log and metric queries (both range and instant) when TSDB is used: - `max_query_bytes_read`: Refuse queries that would read more than the configured bytes here. Overall limit regardless of splitting/sharding. The goal is to refuse queries that would take too long. The default value of 0 disables this limit. - `max_querier_bytes_read`: Refuse queries in which any of their subqueries after splitting and sharding would read more than the configured bytes here. The goal is to avoid a querier from running a query that would load too much data in memory and can potentially get OOMed. The default value of 0 disables this limit. These new limits can be configured per tenant and per query (see https://github.com/grafana/loki/pull/8727). The bytes a query would read are estimated through TSDB's index stats. Even though they are not exact, they are good enough to have a rough estimation of whether a query is too big to run or not. For more details on this refer to this discussion in the PR: https://github.com/grafana/loki/pull/8670#discussion_r1124858508. Both limits are implemented in the frontend. Even though we considered implementing `max_querier_bytes_read` in the querier, this way, the limits for pre and post splitting/sharding queries are enforced close to each other on the same component. Moreover, this way we can reduce the number of index stats requests issued to the index gateways by reusing the stats gathered while sharding the query. With regard to how index stats requests are issued: - We parallelize index stats requests by splitting them into queries that span up to 24h since our indices are sharded by 24h periods. On top of that, this prevents a single index gateway from processing a single huge request like `{app=~".+"} for 30d`. - If sharding is enabled and the query is shardable, for `max_querier_bytes_read`, we re-use the stats requests issued by the sharding ware. Specifically, we look at the [bytesPerShard][1] to enforce this limit. Note that once we merge this PR and enable these limits, the load of index stats requests will increase substantially and we may discover bottlenecks in our index gateways and TSDB. After speaking with @owen-d, we think it should be fine as, if needed, we can scale up our index gateways and support caching index stats requests. Here's a demo of this working: <img width="1647" alt="image" src="https://user-images.githubusercontent.com/8354290/226918478-d4b6c2fd-de4d-478a-9c8b-e38fe148fa95.png"> <img width="1647" alt="image" src="https://user-images.githubusercontent.com/8354290/226918798-a71b1db8-ea68-4d00-933b-e5eb1524d240.png"> Which issue(s) this PR fixes: This PR addresses https://github.com/grafana/loki-private/issues/674. Special notes for your reviewer: - @jeschkies has reviewed the changes related to query-time limits. - I've done some refactoring in this PR: - Extracted logic to get stats for a set of matches into a new function [getStatsForMatchers][2]. - Extracted the _Handler_ interface implementation for [queryrangebase.roundTripper][3] into a new type [queryrangebase.roundTripperHandler][4]. This is used to create the handler that skips the rest of configured middlewares when sending an index stat quests ([example][5]).

Karsten Jeschkies	94725e7908	Define `RequiredLabels` query limit. (#8851 ) What this PR does / why we need it: Some end-users can impose great workload on a cluster by selecting too many streams in their queries. We should be able to limit them. Therefore we introduce a new limit `RequiredLabelMatchers` which list label names that must be included in the stream selectors. The implementation follows the same approach as for max query limit.

Callum Styan	5a85f6647e	Add initial implementation of per-query limits (#8727 ) What this PR does / why we need it: Sometimes we want to limit the impact of a single query by imposing limits that are stricter than the current tenant limit. E.g. the maximum query length could be seven days but based on the query or an admins decision a query should just have a maximum length of one day. This is where per-request limits come into play. They are passed via the `X-Loki-Query-Limit` header and extracted into the requests context. It is the responsibility of the operator or admin that the header is valid.

I was able to reproduce this error via a test that calculates `WeightedParallelism` with a start that's after the end. Not sure if this is possible, but we definitely saw this happening in our ops environment, so something is causing it, and the fix should guard against it in any case.

Owen Diehl	22089415e8	Split parallelism across Period Configs (#7769 ) One of things we watch while updating non-TSDB period configs to TSDB period configs is the difference in query parallelism. TSDB dynamically shards queries into (potentially) much smaller units of work compared to the static shard factors uses prior. To account for this, we use much higher query parallelism configurations with TSDB period configs. This creates a potential problem when querying across `non-tsdb, tsdb` period boundaries: we may want a query parallelism of 512 for the tsdb portion but only 64 for the non-tsdb portion! However, we only had one limit to specify this per tenant, meaning this would be too high when querying non-tsdb periods or too low when querying tsdb ones. This PR * Introduces `tsdb_max_query_parallelism` (default `512`) to `limits_config` * Uses `tsdb_max_query_parallelism` and `max_query_parallelism` limits to find a better parallelism _per query_ by weighting the two respective configs by the proportion of each query spent on TSDB or non-TSDB period configurations.

Karsten Jeschkies	3d5a3936d1	Support limits in multi-tenant queries. (#5626 ) What this PR does / why we need it: This changes adds support for the the following limits in multi-tenant queries: - `MaxQuerySeries` - `QuerySplitDuration` - `MaxEntriesLimitPerQuery` - `MinShardingLookback` - `MaxQueryLength` - `MaxQueryParallelism` - `MaxQueriersPerUser` - `MaxCacheFreshness` It always uses the more restricted limit. That means the smallest `MaxQuerySeries` but biggest `QuerySplitDuration`. The split duration is special. Zero means disabled. Also, the global default resolver is the multi tenant resolver when multi-tenant queries are enabled. This will result HTTP 400 errors in case the user sends multiple tenants to endpoints that do not support it.
