Karsten Jeschkies	5b8d0e666d	Remove querier wait time metric. (#11233 ) What this PR does / why we need it: We would like to know how long a querier worker is idle to understand if workstealing would have an impact. The original metric was too noisy and its cardinality was too high. Instead, we are going to log the wait time.

Michel Hollands	8628b15624	Use metrics namespace for more metrics (#11025 ) What this PR does / why we need it: Use the metrics namespace setting instead of hardcoding to `cortex`. This is a follow up to (and based on) https://github.com/grafana/loki/pull/11014.

Christian Haudum	27411cff08	Introduce worker queue in bloom gateway (#10976 ) Instead of calling the bloom store directly on each and every request to filter chunk refs based on the given filters, we want to queue requests in per-tenant queues and process batches of requests that can be multiplexed to avoid excessive seeking in the bloom block queriers when checking chunk matches. This PR re-uses the request queue implementation used in the query scheduler. To do so, it moves the queue related code from the scheduler into a separate package `pkg/queue` and renames occurrences of "querier" to "consumer" to be more generic. The bloom gateway instantiates the request queue when starting the service. The gRPC method `FilterChunkRefs` then enqueues incoming requests to that queue. Special notes for your reviewer: For testing purposes, this PR also contains a dummy implementation of the workers. The worker implementation - which includes multiplexing of multiple tasks - is subject to a separate PR. --------- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Karsten Jeschkies	3789f1717c	Set buckets for querier_wait_seconds histogram. (#10334 ) What this PR does / why we need it: We should set buckets for the `querier_wait_seconds` histogram.

Karsten Jeschkies	b1a948e28b	Record waiting time for queriers to receive requests. (#10253 ) What this PR does / why we need it: We want to investigate whether work stealing among queriers would be useful. So we are recording the wait time of queriers for new requests in their queue.

Christian Haudum	0adedfa689	Revert high cardinality metric in scheduler (#8946 ) What this PR does / why we need it: The metrics was useful for initial testing of the new scheduler queue implementation but yields high cardinality metrics, which is not desired. Also, the metric does not add additional value beyond the initial testing phase. Special notes for your reviewer: The metric was introduced with commit `cba31024d4` Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Christian Haudum	cba31024d4	Extend scheduler queue metrics with enqueue/dequeue counters (#8891 ) What this PR does / why we need it: Better o11y of the scheduler. This change yields new metrics with potentially high cardinality on the scheduler. Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
