From 51899b521b8610d6ecd062b8f2f9e5978b18660b Mon Sep 17 00:00:00 2001 From: Ashwanth Date: Tue, 16 Jan 2024 16:07:42 +0530 Subject: [PATCH 01/17] feat(metadata cache): adds max_metadata_cache_freshness (#11682) **What this PR does / why we need it**: Adds `max_metadata_cache_freshness` to limit the metadata requests that get cached. When configured, only metadata requests with end time before `now - max_metadata_cache_freshness` are cacheable. _reason for setting the default to 24h?_ metric results cache can [extract samples for the desired time range from an extent](https://github.com/grafana/loki/blob/b6e64e1ef1fb2a2155661c815d0198e147579c8e/pkg/querier/queryrange/queryrangebase/results_cache.go#L78) since the samples are associated with a timestamp. But the same is not true for metadata caching, it is not possible to extract a subset of labels/series from a cached extent. As a result, we could return inaccurate results, more that what was requested. for ex: returning results from an entire 1h extent for a 5m query Setting `max_metadata_cache_freshness` to 24h should help us avoid caching recent data. For anything older, we would report cached metadata results at a granularity controlled by `split_metadata_queries_by_interval` **Which issue(s) this PR fixes**: Fixes # **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] 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`.

The original limit was 5120 based on some internet searching and a best estimate of what a reasonable limit would be. We have seen use cases with queries containing a lot of filter expressions or long expanded variable names where this limit was too small.

FieldDescription
-syncPeriod
- - -Kubernetes meta/v1.Duration - - -		 -(Optional) -

SyncPeriod determines the minimum frequency at which watched resources are -reconciled. A lower period will correct entropy more quickly, but reduce -responsiveness to change if there are many watched resources. Change this -value only if you know what you are doing. Defaults to 10 hours if unset. -there will a 10 percent jitter between the SyncPeriod of all controllers -so that all controllers will not send list requests simultaneously.

-
-leaderElection
- - -Kubernetes v1alpha1.LeaderElectionConfiguration - - -		 -(Optional) -

LeaderElection is the LeaderElection config to be used when configuring -the manager.Manager leader election

-
-cacheNamespace
- -string - -		 -(Optional) -

CacheNamespace if specified restricts the manager’s cache to watch objects in -the desired namespace Defaults to all namespaces

-

Note: If a namespace is specified, controllers can still Watch for a -cluster-scoped resource (e.g Node). For namespaced resources the cache -will only hold objects from the desired namespace.

-
-gracefulShutDown
- - -Kubernetes meta/v1.Duration - - -		 -

GracefulShutdownTimeout is the duration given to runnable to stop before the manager actually returns on stop. -To disable graceful shutdown, set to time.Duration(0) -To use graceful shutdown without timeout, set to a negative duration, e.G. time.Duration(-1) -The graceful shutdown is skipped for safety reasons in case the leader election lease is lost.

Controller contains global configuration options for controllers -registered within this manager.

This bug hadn't surfaced yet (for us) because we've historically used ~6m `chunk-retain` periods which masked this problem (chunks were kept around so we didn't see read gaps). Fixing this bug should allow us to avoid retaining chunks post-flush in ingester memory in TSDB since it doesn't utilize the index-cache (which was the other reason for retaining chunks in memory). This is very attractive because it allows us to reduce memory pressure in ingesters as well as reduces the data they query since now ingesters will only return the chunk references. This allows queriers to download chunks directly rather than ingesters iterating the chunk data for flushed chunks themselves. Also does some refactoring to make testing validation easier. --- .../shipper/indexshipper/tsdb/head_manager.go | 103 ++++++++++-------- .../indexshipper/tsdb/head_manager_test.go | 57 +++++++++- 2 files changed, 112 insertions(+), 48 deletions(-) diff --git a/pkg/storage/stores/shipper/indexshipper/tsdb/head_manager.go b/pkg/storage/stores/shipper/indexshipper/tsdb/head_manager.go index d9f6382c2d2b..bae41255554d 100644 --- a/pkg/storage/stores/shipper/indexshipper/tsdb/head_manager.go +++ b/pkg/storage/stores/shipper/indexshipper/tsdb/head_manager.go @@ -144,66 +144,75 @@ func NewHeadManager(name string, logger log.Logger, dir string, metrics *Metrics return m } -func (m *HeadManager) loop() { - defer m.wg.Done() +func (m *HeadManager) buildPrev() error { + if m.prev == nil { + return nil + } - buildPrev := func() error { - if m.prev == nil { - return nil - } + if err := m.buildTSDBFromHead(m.prevHeads); err != nil { + return err + } - if err := m.buildTSDBFromHead(m.prevHeads); err != nil { - return err - } + // Now that the tsdbManager has the updated TSDBs, we can remove our references + m.mtx.Lock() + defer m.mtx.Unlock() + // We nil-out the previous wal to signal that we've built the TSDBs from it successfully. + // We don't nil-out the heads because we need to keep the them around + // in order to serve queries for the recently rotated out period until + // the index-gws|queriers have time to download the new TSDBs + m.prev = nil - // Now that the tsdbManager has the updated TSDBs, we can remove our references - m.mtx.Lock() - defer m.mtx.Unlock() - m.prevHeads = nil - m.prev = nil + return nil +} - return nil +// tick handles one iteration for `loop()`.
