  • [CHANGE] Azure Storage: Upgraded objstore dependency and support Azure Workload Identity Authentication. Added connection_string to support authenticating via SAS token. Marked msi_resource config as deprecating. #5645
  • [CHANGE] Store Gateway: Add a new fastcache based inmemory index cache. #5619
  • [CHANGE] Index Cache: Multi level cache backfilling operation becomes async. Added -blocks-storage.bucket-store.index-cache.multilevel.max-async-concurrency and -blocks-storage.bucket-store.index-cache.multilevel.max-async-buffer-size configs and metric cortex_store_multilevel_index_cache_backfill_dropped_items_total for number of dropped items. #5661
  • [CHANGE] Ingester: Disable uploading compacted blocks and overlapping compaction in ingester. #5735
  • [CHANGE] Distributor: Count the number of rate-limited samples in distributor_samples_in_total. #5714
  • [CHANGE] Ruler: Remove cortex_ruler_write_requests_total, cortex_ruler_write_requests_failed_total, cortex_ruler_queries_total, cortex_ruler_queries_failed_total, and cortex_ruler_query_seconds_total metrics for the tenant when the ruler deletes the manager for the tenant. #5772
  • [CHANGE] Main: Mark mem-ballast-size-bytes flag as deprecated. #5816
  • [CHANGE] Querier: Mark -querier.ingester-streaming flag as deprecated. Now query ingester streaming is always enabled. #5817
  • [CHANGE] Compactor/Bucket Store: Added -blocks-storage.bucket-store.block-discovery-strategy to configure different block listing strategy. Reverted the current recursive block listing mechanism and use the strategy Concurrent as in 1.15. #5828
  • [CHANGE] Compactor: Don't halt compactor when overlapped source blocks detected. #5854
  • [CHANGE] S3 Bucket Client: Expose -blocks-storage.s3.send-content-md5 flag and set default checksum algorithm to MD5. #5870
  • [CHANGE] Querier: Mark querier.iterators and querier.batch-iterators flags as deprecated. Now querier always use batch iterators. #5868
  • [FEATURE] OTLP ingestion experimental. #5813
  • [FEATURE] Ingester: Add per-tenant new metric cortex_ingester_tsdb_data_replay_duration_seconds. #5477
  • [FEATURE] Query Frontend/Scheduler: Add query priority support. #5605
  • [FEATURE] Tracing: Add kuberesolver to resolve endpoints address with kubernetes:// prefix as Kubernetes service. #5731
  • [FEATURE] Tracing: Add tracing.otel.round-robin flag to use round_robin gRPC client side LB policy for sending OTLP traces. #5731
  • [FEATURE] Ruler: Add ruler.concurrent-evals-enabled flag to enable concurrent evaluation within a single rule group for independent rules. Maximum concurrency can be configured via ruler.max-concurrent-evals. #5766
  • [FEATURE] Distributor Queryable: Experimental: Add config zone_results_quorum_metadata. When querying ingesters using metadata APIs such as label names and values, only results from quorum number of zones will be included and merged. #5779
  • [FEATURE] Storage Cache Clients: Add config set_async_circuit_breaker_config to utilize the circuit breaker pattern for dynamically thresholding asynchronous set operations. Implemented in both memcached and redis cache clients. #5789
  • [FEATURE] Ruler: Add experimental experimental.ruler.api-deduplicate-rules flag to remove duplicate rule groups from the Prometheus compatible rules API endpoint. Add experimental ruler.ring.replication-factor and ruler.ring.zone-awareness-enabled flags to configure rule group replication, but only the first ruler in the replicaset evaluates the rule group, the rest will just hold a copy as backup. Add experimental experimental.ruler.api-enable-rules-backup flag to configure rulers to send the rule group backups stored in the replicaset to handle events when a ruler is down during an API request to list rules. #5782
  • [ENHANCEMENT] Store Gateway: Added -store-gateway.enabled-tenants and -store-gateway.disabled-tenants to explicitly enable or disable store-gateway for specific tenants. #5638
  • [ENHANCEMENT] Compactor: Add new compactor metric cortex_compactor_start_duration_seconds. #5683
  • [ENHANCEMENT] Index Cache: Multi level cache adds config max_backfill_items to cap max items to backfill per async operation. #5686
  • [ENHANCEMENT] Query Frontend: Log number of split queries in query stats log. #5703
  • [ENHANCEMENT] Logging: Added new options for logging HTTP request headers: -server.log-request-headers enables logging HTTP request headers, -server.log-request-headers-exclude-list allows users to specify headers which should not be logged. #5744
  • [ENHANCEMENT] Query Frontend/Scheduler: Time check in query priority now considers overall data select time window (including range selectors, modifiers and lookback delta). #5758
  • [ENHANCEMENT] Querier: Added querier.store-gateway-query-stats-enabled to enable or disable store gateway query stats log. #5749
  • [ENHANCEMENT] AlertManager: Retrying AlertManager Delete Silence on error #5794
  • [ENHANCEMENT] Ingester: Add new ingester metric cortex_ingester_max_inflight_query_requests. #5798
  • [ENHANCEMENT] Query: Added query_storage_wall_time to Query Frontend and Ruler query stats log for wall time spent on fetching data from storage. Query evaluation is not included. #5799
  • [ENHANCEMENT] Query: Added additional max query length check at Query Frontend and Ruler. Added -querier.ignore-max-query-length flag to disable max query length check at Querier. #5808
  • [ENHANCEMENT] Querier: Add context error check when converting Metrics to SeriesSet for GetSeries on distributorQuerier. #5827
  • [ENHANCEMENT] Ruler: Improve GetRules response time by refactoring mutexes and introducing a temporary rules cache in ruler/manager.go. #5805
  • [ENHANCEMENT] Querier: Add context error check when merging slices from ingesters for GetLabel operations. #5837
  • [ENHANCEMENT] Ring: Add experimental -ingester.tokens-generator-strategy=minimize-spread flag to enable the new minimize spread token generator strategy. #5855
  • [ENHANCEMENT] Query Frontend: Ensure error response returned by Query Frontend follows Prometheus API error response format. #5811
  • [ENHANCEMENT] Ring Status Page: Add Ownership Diff From Expected column in the ring table to indicate the extent to which the ownership of a specific ingester differs from the expected ownership. #5889
  • [BUGFIX] Distributor: Do not use label with empty values for sharding #5717
  • [BUGFIX] Query Frontend: queries with negative offset should check whether it is cacheable or not. #5719
  • [BUGFIX] Redis Cache: pass cache_size config correctly. #5734
  • [BUGFIX] Distributor: Shuffle-Sharding with IngestionTenantShardSize == 0, default sharding strategy should be used #5189
  • [BUGFIX] Cortex: Fix GRPC stream clients not honoring overrides for call options. #5797
  • [BUGFIX] Ring DDB: Fix lifecycle for ring counting unhealthy pods as healthy. #5838
  • [BUGFIX] Ring DDB: Fix region assignment. #5842
