Christian Haudum	b75eacc288	chore(blooms)!: Remove bloom compactor component (#13969) ... **What this PR does / why we need it**: This commit removes the code related to the bloom compactor which is superseded by the bloom planner and builders. A handful of CLI arguments of per-tenant settings changed their prefix from `-bloom-compactor.*` to `-bloom-build.*`. Other settings for the compactor component itself, also prefixed with `-bloom-compactor.*` were removed. See upgrade docs for further information. **Special notes for your reviewer**: ✔️ Part of https://github.com/grafana/loki/issues/13957 📔 Documentation update https://github.com/grafana/loki/pull/13965 ⚠️ Integrating the bloom planner and builder into the `backend` target is done in a follow-up PR. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago

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/`. **Checklist** - [X] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [X] Documentation added - [X] Tests updated - [x] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [X] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

Also enforces users to think about what labels are being added. | **Special notes for your reviewer**: regarding `TestQueryTSDB_WithCachedPostings`: removed the assert on get calls as this is hard to get right (splits, querySize mw making stats calls) validating additions to the cache and misses is more important here I think. **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] Tests updated - [x] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [x] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.
