Christian Haudum	be8b4eece3	Scheduler: Add query fairness control across multiple actors within a tenant (#8752 ) What this PR does / why we need it: This PR wires up the scheduler with the hierarchical queues. It is the last PR to implement https://github.com/grafana/loki/pull/8585. When these changes are in place, the client performing query requests can control their QoS (query fairness) using the `X-Actor-Path` HTTP header. This header controls in which sub-queue of the tenant's scheduler queue the query request is enqueued. The place within the hierarchy where it is enqueued defines the probability with which the request gets dequeued. A common use-case for this QoS control is giving each Grafana user within a tenant their fair share of query execution time. Any documentation is still missing and will be provided by follow-up PRs.

Christian Haudum	22b672986a	Revert "Implement hierarchical queues for query scheduler" (#8796 ) Reverts grafana/loki#8691 These changes caused problems with the scheduler in our dev environments. I will conduct further testing and include the reverted changes in https://github.com/grafana/loki/pull/8752	2 years ago
Christian Haudum	4b74a5b815	Implement hierarchical queues for query scheduler (#8691 ) ### What this PR does / why we need it: This PR is the first step towards hierarchical queues within the query scheduler. Hierarchical queues can be used to ensure query fairness across multiple actors within a single tenant, such as individual (human) users using the same tenant. The change is described in the LID ["Query fairness across users within tenants"](https://grafana.com/docs/loki/next/lids/0003-queryfairnessinscheduler/). * Extract metrics for `RequestQueue` into their own `metrics` field, so that they can extended and passed more easily in the future. * Move mapping for tenant queues into its own data structure (ordered map) so its functionality can be reused. It also simplifies the code inside the `tenantQueues` struct. * Add the `LeafQueue` struct that implements hierarchical queues. Sub-queues are dequeued in a round-robin manner using the same implementation of `Mapping` that is also used by the tenant queues. ### Special notes for your reviewer Part of https://github.com/grafana/loki/pull/8585 Contains the changes from PR https://github.com/grafana/loki/pull/8722 This PR does not yet make use of the new hierarchical queues, it only adds the relevant data structures. Wiring up will be done in a follow up PR. While the new `Mapping` data structure adds an unsignificant overhead to the time/op I consider the simplification an overall better tradeoff. ```console $ benchstat scheduler-bench-old.txt scheduler-bench-new.txt name old time/op new time/op delta GetNextRequest-8 18.0µs ± 2% 20.5µs ± 3% +13.89% (p=0.008 n=5+5) QueueRequest-8 56.6µs ± 0% 53.5µs ± 3% -5.48% (p=0.008 n=5+5) name old alloc/op new alloc/op delta GetNextRequest-8 1.60kB ± 0% 1.60kB ± 0% ~ (all equal) QueueRequest-8 35.6kB ± 0% 29.8kB ± 0% -16.37% (p=0.008 n=5+5) name old allocs/op new allocs/op delta GetNextRequest-8 100 ± 0% 100 ± 0% ~ (all equal) QueueRequest-8 819 ± 0% 806 ± 0% -1.59% (p=0.008 n=5+5) ``` #### Complexity of operations \| Operation \| Function \| Complexity \| \| --------- \| -------- \| ---------- \| \| Insert \| `Put(key string, value tenantQueue) bool` \| `O(1)`\| \| Select \| `GetNext(idx QueueIndex) tenantQueue` \| `O(1)` (best case) `O(n)` (worst case) \| \| Remove \| `Remove(key string) bool` \| `O(1)` \| --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago

Christian Haudum	17577b4d47	Shut down query frontend gracefully (#7978 ) What this PR does / why we need it: This PR fixes a bug in the shutdown process of the query frontend. In order to shut down the frontend gracefully without cancelling any in-flight operations/sub-requests, the frontend service has to wait until all in-flight operations are finished. Only then its sub-services may be stopped. In order to control the deterministic order of the shutdown of the service and its child services, child services need to be started with their own context (not with their parent context). Otherwise, if the context of the frontend is cancelled, also the contexts of the child services are cancelled, leading to a parallel stopping of the parent and its child services. During the time of the shutdown, the `RoundTripGRCP` function still needs to accept any round-tripping requests. This is, because the frontend round tripper is wrapped into a query range tripper ware, which splits incoming (HTTP) query requests into multiple (gRPC) query requests if needed. Which issue(s) this PR fixes: This fixes a race condition where queries fail, because the query frontend shut down before the queriers that processed in-flight request could send the query response to the frontend. This manifested in an increased error rate of queries during restarts (rollouts) of the query frontend.

Requirements: * CI `check` pipeline should fail if the documentation file is updated manually * CI `check` pipeline should fail if registration flags are changed in the code, but the documentation file is not generated.

Susana Ferreira	f93b91bfb5	Add configuration documentation generation tool (#7916 ) What this PR does / why we need it: Add a tool to generate configuration flags documentation based on the flags properties defined on registration on the code. This tool is based on the [Mimir doc generation tool](https://github.com/grafana/mimir/tree/main/tools/doc-generator) and adapted according to Loki configuration specifications. Prior to this PR, the configuration flags documentation was dispersed across two sources: * [_index.md](`5550cd65ec/docs/sources/configuration/_index.md`) * configuration flags registration in the code This meant that there was no single source of truth. In this PR, the previous `_index.md` file is replaced with the new file generated by the tool. The next step includes adding a CI step that validates if the _index.md file was generated according to the flags settings. This will be done in a follow-up PR. NOTE: this is not a documentation update PR. Apart from some minor typo fixes, the documentation changes on the code, were copied from the `_index.md` file. Which issue(s) this PR fixes: Fixes https://github.com/grafana/loki-private/issues/83 Special notes for your reviewer: Files: * [docs/sources/configuration/index.template](`5550cd65ec/docs/sources/configuration/index.template`): template used to generate the final configuration file * [/docs/sources/configuration/_index.md](`c32e5d0acb/docs/sources/configuration/_index.md`): file generated by tool * `loki/pkg` directory files updated with up-to-date documentation from `_index.md` file * [tools/doc-generator](`5550cd65ec/tools/doc-generator`) directory with documentation generation tool.
