Lots of improvements this release! Outstanding items:

  • First Katacoda tutorial! 🐱
  • Fixed Deletion order causing Compactor to produce not needed 👻 blocks with missing random files.
  • Store GW memory improvements (more to come!).
  • Querier allows multiple deduplication labels.
  • Both Compactor and Store Gateway can be sharded within the same bucket using relabelling!
  • Sidecar exposed data from Prometheus can be now limited to given min-time (e.g 3h only).
  • Numerous Thanos Receive improvements.

Make sure you check out Prometheus 2.13.0 as well. New release drastically improves usage and resource consumption of both Prometheus and sidecar with Thanos: https://prometheus.io/blog/2019/10/10/remote-read-meets-streaming/

  • #1533 Thanos inspect now supports the timeout flag.
  • #1496 Thanos Receive now supports setting block duration.
  • #1362 Optional replicaLabels param for /query and
    /query_range querier endpoints. When provided overwrite the query.replica-label cli flags.

  • #1612 Thanos Rule added resendDelay flag.
  • #1480 Thanos Receive flushes storage on hashring change.

Changed

  • #1362 query.replica-label configuration can be provided more than
    once for multiple deduplication labels like: --query.replica-label=prometheus_replica --query.replica-label=service.
  • #1581 Thanos Store now can use smaller buffer sizes for Bytes pool; reducing memory for some requests.
  • #1622 & #1590 Updated to Go 1.13.1
  • #1498 Thanos Receive change flag labels to label to be consistent with other commands.

Fixed

  • #1525 Thanos now deletes block's file in correct order allowing to detect partial blocks without problems.
  • #1505 Thanos Store now removes invalid local cache blocks.
  • #1587 Thanos Sidecar cleanups all cache dirs after each compaction run.
  • #1582 Thanos Rule correctly parses Alertmanager URL if there is more + in it.
  • #1544 Iterating over object store is resilient to the edge case for some providers.
  • #1469 Fixed Azure potential failures (EOF) when requesting more data then blob has.
  • #1512 Thanos Store fixed memory leak for chunk pool.
  • #1488 Thanos Rule now now correctly links to query URL from rules and alerts.
