v0.24.0-rc.0

Pre-release
Pre-release

Added

  • #4228 Tools thanos bucket inspect: Add flag --output to provide output method (table,csv,tsv).
  • #4282 Query: breaking ⚠️ Add --endpoint flag to the querier. The --store flag will eventually be replaced.
  • #4680 Query: Add exemplar.partial-response flag to control partial response.
  • #4679 Query: Add enable-feature flag to enable negative offsets and @ modifier, similar to Prometheus.
  • #4696 Query: Add cache name to tracing spans.
  • #4710 Store: Add metric to capture timestamp of the last loaded block.
  • #4736 S3: Add capability to use custom AWS STS Endpoint.
  • #4764 Compact: Add block-viewer.global.sync-block-timeout flag to set the timeout of synchronization block metas.
  • #4801 Compact: Add Prometheus metrics for tracking the progress of compaction and downsampling.
  • #4444 UI: Add mark deletion and no compaction to the Block UI.
  • #4576 UI: Add filter compaction level to the Block UI.

Notable changes:

  • Query-frontend overhead reduced 20% (change your max_idle_conns_per_host to at least 100!)
  • Massive enhancement over Block UI: Search capabilities, overlap finder and more!
  • Added Baidu BOS object storage support
  • Improved tracing metadata. It now shows exact series, samples and overall bytes processes per component in the path of StoreAPI.Series query.
  • Easier use of non Store APIs: auto-discovery through endpoint flag. Old components will work as they were, no action is required unless you want to explicitly disable certain APIs (e.g rules, exemplars, metadata etc) if you don't want them.
  • Added few Prometheus PromQL functions (upgraded Prometheus deps)

Added

  • #4453 Tools thanos bucket web: Add flag --selector.relabel-config-file / --selector.relabel-config / --max-time / --min-time to filter served blocks.
  • #4482 Store: Add http_config option for COS object store client.
  • #4487 Query/Store: Add memcached auto discovery support for all caching clients.
  • #4444 UI: Add search to the Block UI.
  • #4509 Logging: Add duration_ms in int64 to the logs for easier log filtering.
  • #4462 UI: Highlighting blocks overlap in the Block UI.
  • #4469 Compact: Add flag compact.skip-block-with-out-of-order-chunks to skip blocks with out-of-order chunks during compaction instead of halting.
  • #4506 Store: Add Baidu BOS object storage, see documents for further information.
  • #4552 Compact: Add thanos_compact_downsample_duration_seconds histogram metric.
  • #4594 Reloader: Expose metrics in config reloader to give info on the last operation.
  • #4619 Tracing: Added consistent tags to Series call from Querier about number important series statistics: processed.series, processed.samples, processed.samples and processed.bytes. This will give admin idea of how much data each component processes per query.
  • #4623 Query-frontend: Make HTTP downstream tripper (client) configurable via parameters --query-range.downstream-tripper-config and --query-range.downstream-tripper-config-file. If your downstream URL is localhost or 127.0.0.1 then it is strongly recommended to bump max_idle_conns_per_host to at least 100 so that query-frontend could properly use HTTP keep-alive connections and thus reduce the latency of query-frontend by about 20%.

Fixed

  • #4468 Rule: Fix temporary rule filename composition issue.
  • #4476 UI: Fix incorrect html escape sequence used for '>' symbol.
  • #4532 Mixin: Fix "all jobs" selector in thanos mixin dashboards.
  • #4607 Azure: Fix Azure MSI Rate Limit.

Changed

  • #4519 Query: Switch to miekgdns DNS resolver as the default one.
  • #4586 Update Prometheus/Cortex dependencies and implement LabelNames() pushdown as a result; provides massive speed-up for the labels API in Thanos Query.
  • #4421 breaking ⚠️: --store (in the future, to be renamed to --endpoints) now supports passing any APIs from Thanos gRPC APIs: StoreAPI, MetadataAPI, RulesAPI, TargetsAPI and ExemplarsAPI (in oppose in the past you have to put it in hidden --targets, --rules etc flags). --store will now automatically detect what APIs server exposes.
  • #4669 Moved Prometheus dependency to v2.30.

Highlights

  • Added offline deduplication that helps saving even more space on the remote object storage & increases query performance
  • The receive dual-mode has been implemented
  • Receive now is able to ingest exemplars and it is possible to query them
  • Receive now uses a few percent less of CPU time with the same load
  • Azure object storage has been refactored to support MSI authentication & it's now much more configurable

This release contains improvements from 28 authors (git log --pretty="%ae" origin/release-0.21...origin/release-0.22 | sort | uniq | wc -l)! Thanks to all of them! Thanos wouldn't be what it is without all of their effort and time! ❤️

Added

  • #4394 Add error logs to receiver when write request rejected with invalid replica
  • #4403 UI: Add sorting and filtering to flags page
  • #4299 Tracing: Add tracing to exemplar APIs.
  • #4327 Add environment variable substitution to all YAML configuration flags.
  • #4239 Add penalty based deduplication mode for compactor.

  • #4348 Fixed parsing of the port in the log middleware.
  • #4417 UI: fixed the night mode in Bucket UI.
  • #4442 Ruler: fix SIGHUP reload signal not working.

Changed

  • #4354 Receive: use the S2 library for decoding Snappy data; saves about 5-7% of CPU time in the Receive component when handling incoming remote write requests
  • #4369 Build: Pin upgrade Alpine's version.
  • #4404 Receive: added extra validation for the tenant's label name. Some unsupported formats could have passed before.
