From d97ac48681d676486fa4d184043b0978ccf120d1 Mon Sep 17 00:00:00 2001 From: Salva Corts Date: Fri, 26 Jan 2024 13:51:16 +0100 Subject: [PATCH 01/26] Add timing metrics for compaction (#11785) **What this PR does / why we need it**: This PR modifies the metrics of the bloom compactor to: - Add new histogram metrics to track the time spent to process compaction cycles, tenants and jobs. - Replace `_succeeded` and `_failed` metrics with a new `_completed` metric with a status label. **Which issue(s) this PR fixes**: Fixes # **Special notes for your reviewer**: **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] 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`. [Example PR](https://github.com/grafana/loki/commit/d10549e3ece02120974929894ee333d07755d213) - [ ] 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.

I believe that there are two reasons why this test is flaky: - the test expects that the 5 last lines of logs are the expected ones but it seems that other lines might be logged as well (https://drone.grafana.net/grafana/agent/16045/4/2) - we saw that the simulated container did not always have enough time to stop before calling the tgt.startIfNotRunning() to restart it. (https://drone.grafana.net/grafana/agent/16077/4/2) Fix: - the test now uses "assert.EventuallyWithT" and checks that within 5 seconds the expected log lines will be amongst the logs without duplicate. -

It also handles errors from the shipper in a way that they are returned to the waiting request asap so it can return and does not need to wait for all tasks to finish.

It cleanly separates I/O from logic and therefore is more testable than the current worker implementation. https://github.com/grafana/loki/blob/9602214abf5f0b016f1cad90e921d1e4d969856c/pkg/bloomgateway/processor.go#L33-L36 **Note**: The processor is not used yet in the worker. **Certain parts must be refactored when #11810 is merged.** --------- Signed-off-by: Christian Haudum --- pkg/bloomcompactor/bloomcompactor.go | 8 +- pkg/bloomgateway/bloomgateway_test.go | 125 -----------

Diachenko <82767850+vlad-diachenko@users.noreply.github.com> Date: Tue, 30 Jan 2024 14:16:47 +0200 Subject: [PATCH 12/26] DequeueMany fix (#11797) **What this PR does / why we need it**: Previously we relied only on the index of the tenant's queue to read the requests from the same tenant's queue. However, as long as the queue is aggressively used by the consumers in parallel, there are a few edge cases when knowing the index of last used tenant's queue is not enough to guarantee that we dequeue items from exactly the same tenant's queue. **Special notes for your reviewer**: **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [x] Tests updated - [ ] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] 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`. [Example PR](https://github.com/grafana/loki/commit/d10549e3ece02120974929894ee333d07755d213) - [ ] 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.

The store holds a store entry for each schema period. * The `bloomStoreEntry` implements the `Store` and `Client` interfaces. It holds a bloom client for a single schema period. Additionally, the store entry also exposes a fetcher for metas (and in the future for blocks), which is responsible for getting data from cache or storage (if not available in cache). * The `BloomClient` implement the `Client` interface. The bloom client uses an object client for the schema period of the bloom client. * The `Fetcher` can fetch and cache metas. This structure is very similar to what we use for the chunk store. **Note** Before implementing `FetchBlocks()` in the `BloomStore`, I want to implement the new `FingerprintBounds` type also in the shipper and bloom gateway code to be consistent across components, as well as to make use of the new utilities exposed by them. The store implementation probably needs some specific test cases around using the correct store entry for different schema period configs. The code however is mostly taken from the chunk store implementation. --------- Signed-off-by: Christian Haudum --- pkg/bloomcompactor/bloomcompactor.go | 20 +- pkg/bloomgateway/bloomgateway.go | 9 +- pkg/bloomgateway/processor.go | 8 +- pkg/bloomgateway/processor_test.go | 18 +- .../stores/shipper/bloomshipper/client.go | 187 +++----- .../shipper/bloomshipper/client_test.go | 97 ++--- .../stores/shipper/bloomshipper/fetcher.go | 178 ++++++++ .../shipper/bloomshipper/fetcher_test.go | 176 ++++++++ .../stores/shipper/bloomshipper/shipper.go | 16 +- .../stores/shipper/bloomshipper/store.go | 404 ++++++++++++++++++ 10 files changed, 899 insertions(+), 214 deletions(-) create mode 100644 pkg/storage/stores/shipper/bloomshipper/fetcher.go create mode 100644 pkg/storage/stores/shipper/bloomshipper/fetcher_test.go create mode 100644 pkg/storage/stores/shipper/bloomshipper/store.go diff --git a/pkg/bloomcompactor/bloomcompactor.go b/pkg/bloomcompactor/bloomcompactor.go index 5cb64a350d161..52799e498b51e 100644 --- a/pkg/bloomcompactor/bloomcompactor.go +++ b/pkg/bloomcompactor/bloomcompactor.go @@ -27,6 +27,7 @@ package bloomcompactor import ( "context" "fmt" + "io" "math" "math/rand" "os" @@ -50,6 +51,7 @@ import ( "github.com/grafana/loki/pkg/bloomutils" "github.com/grafana/loki/pkg/storage" v1 "github.com/grafana/loki/pkg/storage/bloom/v1" + "github.com/grafana/loki/pkg/storage/chunk/cache" chunk_client "github.com/grafana/loki/pkg/storage/chunk/client" "github.com/grafana/loki/pkg/storage/chunk/client/local" "github.com/grafana/loki/pkg/storage/config" @@ -71,7 +73,7 @@ type Compactor struct { limits Limits // temporary workaround until store has implemented read/write shipper interface - bloomShipperClient bloomshipper.Client + bloomShipperClient bloomshipper.StoreAndClient // Client used to run operations on the bucket storing bloom blocks. storeClients map[config.DayTime]storeClient @@ -109,8 +111,10 @@ func New( reg: r, } - // Configure BloomClient for meta.json management - bloomClient, err := bloomshipper.NewBloomClient(schemaConfig.Configs, storageCfg, clientMetrics) + // TODO(chaudum): Plug in cache + var metasCache cache.Cache + var blocksCache *cache.EmbeddedCache[string, io.ReadCloser] + bloomClient, err := bloomshipper.NewBloomStore(schemaConfig.Configs, storageCfg, clientMetrics, metasCache, blocksCache, logger) if err != nil { return nil, err } @@ -506,11 +510,19 @@ func (c *Compactor) runCompact(ctx context.Context, logger log.Logger, job Job, //TODO Configure pool for these to avoid allocations var activeBloomBlocksRefs []bloomshipper.BlockRef - metas, err := c.bloomShipperClient.GetMetas(ctx, metaSearchParams) + metaRefs, fetchers, err := c.bloomShipperClient.ResolveMetas(ctx, metaSearchParams) if err != nil { return err } + for i := range fetchers { + res, err := fetchers[i].FetchMetas(ctx, metaRefs[i]) + if err != nil { + return err + } + metas = append(metas, res...) + } + // TODO This logic currently is NOT concerned with cutting blocks upon topology changes to bloom-compactors. // It may create blocks with series outside of the fp range of the compactor.
