thanos-io/thanos v0.18.0-rc.0

on GitHub

Highlights

• Several big optimizations speeding up query performance were introduced!
• A new command was added, thanos tools bucket rewrite, enabling the deletion of series from given block.
• The Query Frontend now supports proxying requests to the labels and series API endpoints.
• thanos tools bucket replicate can now copy particular blocks by ID.
• The number of series touched by the Store component when servicing a Series call can now be limited using a CLI flag.

Added

• #3380 Mixin: Add block deletion panels for compactor dashboards.
• #3568 Store: Optimized inject label stage of index lookup.
• #3566 StoreAPI: Support label matchers in labels API.
• #3531 Store: Optimized common cases for time selecting smaller amount of series by avoiding looking up symbols.
• #3469 StoreAPI: Added hints field to LabelNamesRequest and LabelValuesRequest. Hints are an opaque data structure that can be used to carry additional information from the store and its content is implementation-specific.
• #3421 Tools: Added thanos tools bucket rewrite command allowing to delete series from given block.
• #3509 Store: Added a CLI flag to limit the number of series that are touched.
• #3444 Query Frontend: Make POST request to downstream URL for labels and series API endpoints.
• #3388 Tools: Bucket replicator now can specify block IDs to copy.
• #3385 Tools: Bucket prints extra statistics for block index with debug log-level.
• #3121 Receive: Added --receive.hashrings alternative to receive.hashrings-file flag (lower priority). The flag expects the literal hashring configuration in JSON format.

Fixed

• #3567 Mixin: Reintroduce thanos_objstore_bucket_operation_failures_total alert.
• #3527 Query Frontend: Fix query_range behavior when start/end times are the same
• #3560 Query Frontend: Allow separate label cache
• #3672 Rule: Prevent crashing due to no such host error when using dnssrv+ or dnssrvnoa+.
• #3461 Compact, Shipper, Store: Fixed panic when no external labels are set in block metadata.

Changed

• #3496 S3: Respect SignatureV2 flag for all credential providers.
• #2732 Swift: Switched to a new library ncw/swift providing large objects support.
  By default, segments will be uploaded to the same container directory segments/ if the file is bigger than 1GB.
  To change the defaults see the docs.
• #3626 Shipper: Failed upload of meta.json file doesn't cause block cleanup anymore. This has a potential to generate corrupted blocks under specific conditions. Partial block is left in bucket for later cleanup.
