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.

[Example PR](`d10549e3ec`) - [ ] If the change is deprecating or removing a configuration option, update the `deprecated-config.yaml` and `deleted-config.yaml` files respectively in the `tools/deprecated-config-checker` directory. <!-- TODO(salvacorts): Add example PR --> --------- Signed-off-by: Michel Hollands <michel.hollands@gmail.com> Co-authored-by: Ashwanth <iamashwanth@gmail.com>	2 years ago
Danny Kopping	beed298549	Dynamic client-side throttling to avoid object storage rate-limits (GCS only) (#10140 ) What this PR does / why we need it: Across the various cloud providers' object storage services, there are different rate-limits implemented. Rate-limits can be imposed under multiple conditions, such as server-side scale up (ramping up from low volume to high, "local" limit), reaching some defined upper limit ("absolute" limit), etc. We cannot know apriori when these rate-limits will be imposed, so we can't set up a client-side limiter to only allow a certain number of requests through per second. Additionally, that would require global coordination between queriers - which is difficult. With the above constraints, I have instead taken inspiration from TCP's [congestion control algorithms](https://en.wikipedia.org/wiki/TCP_congestion_control). This PR implements [AIMD](https://en.wikipedia.org/wiki/Additive_increase/multiplicative_decrease) (Additive Increase, Multiplicative Decrease), which is used in the congestion _avoidance_ phase of congestion control. The default window size (object store requests per second) is 2000; in other words, we skip the "slow start" phase. The controller uses the Go [`rate.Limiter`](https://pkg.go.dev/golang.org/x/time/rate), which implements the token-bucket algorithm. To put it simply: - every successful request widens the window (per second client rate-limit) - every rate-limited response reduces the window size by a backoff factor (0.5 by default, so it will halve) - when the limit has been reached, the querier will be delayed from making further requests until tokens are available	2 years ago
