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. Special notes for your reviewer: ```console $ gotest -count=1 -v ./pkg/scheduler/queue/... -test.run=TestQueryFairness === RUN TestQueryFairness === RUN TestQueryFairness/use_hierarchical_queues_=_false dequeue_qos_test.go:109: duration actor a 2.007765568s dequeue_qos_test.go:109: duration actor b 2.209088331s dequeue_qos_test.go:112: total duration 2.209280772s === RUN TestQueryFairness/use_hierarchical_queues_=_true dequeue_qos_test.go:109: duration actor b 605.283144ms dequeue_qos_test.go:109: duration actor a 2.270931324s dequeue_qos_test.go:112: total duration 2.271108551s --- PASS: TestQueryFairness (4.48s) --- PASS: TestQueryFairness/use_hierarchical_queues_=_false (2.21s) --- PASS: TestQueryFairness/use_hierarchical_queues_=_true (2.27s) PASS ok github.com/grafana/loki/pkg/scheduler/queue 4.491s ``` ```console $ gotest -count=5 -v ./pkg/scheduler/queue/... -bench=Benchmark -test.run=^$ -benchtime=10000x -benchmem goos: linux goarch: amd64 pkg: github.com/grafana/loki/pkg/scheduler/queue cpu: 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz BenchmarkGetNextRequest BenchmarkGetNextRequest/without_sub-queues BenchmarkGetNextRequest/without_sub-queues-8 10000 29337 ns/op 1600 B/op 100 allocs/op BenchmarkGetNextRequest/without_sub-queues-8 10000 21348 ns/op 1600 B/op 100 allocs/op BenchmarkGetNextRequest/without_sub-queues-8 10000 21595 ns/op 1600 B/op 100 allocs/op BenchmarkGetNextRequest/without_sub-queues-8 10000 21189 ns/op 1600 B/op 100 allocs/op BenchmarkGetNextRequest/without_sub-queues-8 10000 21602 ns/op 1600 B/op 100 allocs/op BenchmarkGetNextRequest/with_1_level_of_sub-queues BenchmarkGetNextRequest/with_1_level_of_sub-queues-8 10000 33770 ns/op 2400 B/op 200 allocs/op BenchmarkGetNextRequest/with_1_level_of_sub-queues-8 10000 33596 ns/op 2400 B/op 200 allocs/op BenchmarkGetNextRequest/with_1_level_of_sub-queues-8 10000 34432 ns/op 2400 B/op 200 allocs/op BenchmarkGetNextRequest/with_1_level_of_sub-queues-8 10000 33760 ns/op 2400 B/op 200 allocs/op BenchmarkGetNextRequest/with_1_level_of_sub-queues-8 10000 33664 ns/op 2400 B/op 200 allocs/op BenchmarkGetNextRequest/with_2_levels_of_sub-queues BenchmarkGetNextRequest/with_2_levels_of_sub-queues-8 10000 71405 ns/op 3200 B/op 300 allocs/op BenchmarkGetNextRequest/with_2_levels_of_sub-queues-8 10000 59472 ns/op 3200 B/op 300 allocs/op BenchmarkGetNextRequest/with_2_levels_of_sub-queues-8 10000 117163 ns/op 3200 B/op 300 allocs/op BenchmarkGetNextRequest/with_2_levels_of_sub-queues-8 10000 106505 ns/op 3200 B/op 300 allocs/op BenchmarkGetNextRequest/with_2_levels_of_sub-queues-8 10000 64374 ns/op 3200 B/op 300 allocs/op BenchmarkQueueRequest BenchmarkQueueRequest-8 10000 168391 ns/op 320588 B/op 1156 allocs/op BenchmarkQueueRequest-8 10000 166203 ns/op 320587 B/op 1156 allocs/op BenchmarkQueueRequest-8 10000 149518 ns/op 320584 B/op 1156 allocs/op BenchmarkQueueRequest-8 10000 219776 ns/op 320583 B/op 1156 allocs/op BenchmarkQueueRequest-8 10000 185198 ns/op 320597 B/op 1156 allocs/op PASS ok github.com/grafana/loki/pkg/scheduler/queue 64.648s ``` Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	3 years ago
