  • [FEATURE]: v2 object encoding added. This encoding adds a start/end timestamp to every record to reduce proto marshalling and increase search speed. BREAKING CHANGE After this rollout the distributors will use a new API on the ingesters. As such you must rollout all ingesters before rolling the distributors. Also, during this period, the ingesters will use considerably more resources and as such should be scaled up (or incoming traffic should be heavily throttled). Once all distributors and ingesters have rolled performance will return to normal. Internally we have observed ~1.5x CPU load on the ingesters during the rollout. #1227 (@joe-elliott)

  • [ENHANCEMENT] Add forwarding queue from distributor to metrics-generator. #1331 (@mapno)

    querier:
  search:
    external_hedge_requests_at: 5s
    external_hedge_requests_up_to: 3
    ** BREAKING CHANGE ** Querier options related to search have moved under a search block: 
    querier:
 search_query_timeout: 30s
 search_external_endpoints: []
 search_prefer_self: 2
    becomes 
    querier:
  search:
    query_timeout: 30s

  • [BUGFIX] Fixes min/max time on blocks to be based on span times instead of ingestion time. #1314 (@joe-elliott)
    • Includes new configuration option to restrict the amount of slack around now to update the block start/end time. #1332 (@joe-elliott) 
      storage:
  trace:
    wal:
      ingestion_time_range_slack: 2m0s
    • Includes a new metric to determine how often this range is exceeded: tempo_warnings_total{reason="outside_ingestion_time_slack"}

v1.0.0 / 2021-06-08

  • [CHANGE] Mark -auth.enabled as deprecated. New flag is -multitenancy.enabled and is set to false by default. This is a breaking change if you were relying on auth/multitenancy being enabled by default. #646
  • [ENHANCEMENT] Performance: Improve Ingester Record Insertion. #681
