Dylan Guedes	2f56f50cc6	fix: Transform `ObjectExistsWithSize` into `GetAttributes` (#14329 ) - Transform our `ObjectExistsWithSize` API into `GetAttributes` to conform with the existing Thanos API. - Fix we not returning the size when we should on our s3 implementation of `ObjectSize` - Fix not returning `false, nil` to `ObjectExists` when the only error seen is a `NotFound`. If someone calls `ObjectExists` it should return `false, nil` to a `NotExist` error, instead of `false, err`	1 year ago
Christian Haudum	f52f8ad540	chore: Clarify compression package (#14257 ) This PR renames "encoding" to "codec" in the compression package to remove the cognitive dissonance. It also removes the `Enc` prefix for codec identifiers, so that they adhere Go's best practice of naming conventions, e.g. `compression.EncGZIP` becomes `compression.GZIP` when used in a different package.

Dylan Guedes	ac422b3bc3	feat: Introduce new `ObjectExistsWithSize` API to (#14268 ) What this PR does / why we need it: Introduce a new `ObjectExistsWithSize` API to our object storage interface. This is the same as `ObjectExists` but with the object size as part of the return value. This is useful to compare the object size present.	1 year ago
Christian Haudum	963779064b	chore: Move compression utilities into separate package (#14167 ) Compression tooling has been part of the `chunkenc` (chunk encoding) package in the past for legacy reasons. Since more components use this now, it's easier to keep it in a separate package. This also eliminates the confusion around "encoding", since this has been incorrectly used synonymously with "compression" in the past. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com> Co-authored-by: Robert Fratto <robertfratto@gmail.com>	1 year ago

Christian Haudum	73edf7a943	(chore) Bloomshipper: Separate store and client (#11865 ) What this PR does / why we need it: This PR removes the `StoreAndClient` interface that was accepted by the `BloomShipper`. Since the `BloomStore` had to not only implement the `Store` interface, but also the `Client` interface, it caused re-implementation of the same methods in different ways. Now the shipper solely relies on the `Store` interface. See individual commit messages for more context. Tests have been rewritten from scratch and placed in their own respective test files for store and client. --------- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Shantanu Alshi	fb6f6d2e2f	Stop using global logger in modules (#11051 ) What this PR does / why we need it: Refactors Loki to inject logger from the constructors instead of using global logger variable.

Ashwanth	a118e994d8	Remove shared_store and shared_store_key_prefix from shipper and compactor (#10840 ) What this PR does / why we need it: #### Removes `shared_store` and `shared_store_key_prefix` from index shipper and compactor configs and their corresponding CLI flags. - `-tsdb.shipper.shared-store` - `-boltdb.shipper.shared-store` - `-tsdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.compactor.shared-store` - `-boltdb.shipper.compactor.shared-store.key-prefix` `shared_store` has been a confusing option allowing users to easily misconfigure Loki. Going forward `object_store` setting in the [period_config](https://grafana.com/docs/loki/latest/configure/#period_config) (which already configured the store for chunks) will be used to configure store for the index. And the newly added `path_prefix` option under the `index` key in `period_config` will configure the path under which index tables are stored. This change enforces chunks and index files for a given period reside together in the same storage bucket. More details in the upgrade guide. --- `-compactor.delete-request-store` has to be explicitly configured going forward. Without setting this, loki wouldn't know which object store to use for storing delete requests. Path prefix for storing deletes is decided by `-compactor.delete-request-store.key-prefix` which defaults to `index/`.

Christian Haudum	31981bd4af	Remove dependency on Bigchunk, which is a leftover of Cortex and is only used in tests (#10354 ) What this PR does / why we need it: This PR removes the dependency on "Bigchunk", which is a "default" implementation of the `chunk.Data` interface and used only in tests. Special notes for your reviewer: The PR replaces the usage of this chunk type with the Loki implementation (`chunkenc.MemChunk` wrapped into `chunkenc.Facade`) where possible. In case where it was not possible (tests in `pkg/storage/chunk` package) due to otherwise circular import, it was replaces by the `chunk.dummyChunk` implementation, which is just a no-op that implements `chunk.Data` interface) The PR also removes the protos for the ingester client (`pkg/ingester/client/ingester.proto`) which were only referenced in the removed `pkg/util/chunkcompat/compat.go` file.

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	3 years ago
