Highlights:

  • Fixed very old bug of rare double counter reset accounting when querying rate with deduplication enabled, thanks to @SuperQ who shared raw data, that reproducing this!
  • Thanos Receive is now multitenant 🎉 and closer to claiming production stability 💪
  • Huge movement in moving Thanos UIs to React thanks to our GSoC mentee @prmsrswt !
  • Experimental Memcached caching for metadata and chunks thanks to @pstibrany and Cortex project ❤️
  • Optimized querier for various cases of overlapping data (e.g sidecar + store GW overlap) 📉
  • Thanos Rule and Receive should use less resources thanks to Prometheus improvements 🎉

Fixed

  • #2548 Query: Fixed rare cases of double counter reset accounting when querying rate with deduplication enabled.
  • #2536 S3: Fixed AWS STS endpoint URL to https for Web Identity providers on AWS EKS.
  • #2501 Query: Gracefully handle additional fields in SeriesResponse protobuf message that may be added in the future.
  • #2568 Query: Don't close the connection of strict, static nodes if establishing a connection had succeeded but Info() call failed.
  • #2615 Rule: Fix bugs where rules were out of sync.
  • #2614 Tracing: Disabled Elastic APM Go Agent default tracer on initialization to disable the default metric gatherer.
  • #2525 Query: Fixed logging for dns resolution error in the Query component.
  • #2484 Query/Ruler: Fixed issue #2483, when web.route-prefix is set, it is added twice in HTTP router prefix.
  • #2416 Bucket: Fixed issue #2416 bug in inspect --sort-by doesn't work correctly in all cases

Added

  • #2012 Receive: Added multi-tenancy support (based on the header)
  • #2502 StoreAPI: Added hints field to SeriesResponse. Hints in an opaque data structure that can be used to carry additional information from the store and its content is implementation-specific.
  • #2521 Sidecar: Added thanos_sidecar_reloader_reloads_failed_total, thanos_sidecar_reloader_reloads_total, thanos_sidecar_reloader_watch_errors_total, thanos_sidecar_reloader_watch_events_total and thanos_sidecar_reloader_watches metrics.
  • #2412 UI: Added React UI from Prometheus upstream. Currently only accessible from Query component as only /graph endpoint is migrated.
  • #2532 Store: Added hidden option --store.caching-bucket.config=<yaml content> (or --store.caching-bucket.config-file=<file.yaml>) for experimental caching bucket, that can cache chunks into shared memcached. This can speed up querying and reduce number of requests to object storage.
  • #2579 Store: Experimental caching bucket can now cache metadata as well. Config has changed from #2532.
  • #2621 Receive: Added flag to configure forward request timeout. Receive write will complete request as soon as a quorum of writes succeeds.

Changed

  • #2194 Updated to golang v1.14.2.
  • #2505 Store: Removed obsolete thanos_store_node_info metric.
  • 2513 Tools: Moved thanos bucket commands to thanos tools bucket, also
    moved thanos check rules to thanos tools rules-check. thanos tools rules-check also takes rules by --rules repeated flag not argument
    anymore.
  • #2548 Store, Querier: remove duplicated chunks on StoreAPI.
  • #2596 Updated Prometheus dependency to @cd73b3d33e064bbd846fc7a26dc8c313d46af382 which falls in between v2.17.0 and v2.18.0.
    • Receive,Rule: TSDB now supports isolation of append and queries.
    • Receive,Rule: TSDB now holds less WAL files after Head Truncation.
  • #2450 Store: Added Regex-set optimization for label=~"a|b|c" matchers.
  • #2526 Compact: In case there are no labels left after deduplication via --deduplication.replica-label, assign first replica-label with value deduped.
