released this

01 Feb 19:35 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.

You can’t perform that action at this time.
