v0.23.0-rc.0

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.
