  • [CHANGE] Remove support for chunks storage entirely. If you are using chunks storage on a previous version, you must migrate your data on version 1.12 or earlier. Before upgrading to this release, you should also remove any deprecated chunks-related configuration, as this release will no longer accept that. The following flags are gone:
  • -dynamodb.*
  • -metrics.*
  • -s3.*
  • -azure.*
  • -bigtable.*
  • -gcs.*
  • -cassandra.*
  • -boltdb.*
  • -local.*
  • some -ingester flags:
    • -ingester.wal-enabled
    • -ingester.checkpoint-enabled
    • -ingester.recover-from-wal
    • -ingester.wal-dir
    • -ingester.checkpoint-duration
    • -ingester.flush-on-shutdown-with-wal-enabled
    • -ingester.max-transfer-retries
    • -ingester.max-samples-per-query
    • -ingester.min-chunk-length
    • -ingester.flush-period
    • -ingester.retain-period
    • -ingester.max-chunk-idle
    • -ingester.max-stale-chunk-idle
    • -ingester.flush-op-timeout
    • -ingester.max-chunk-age
    • -ingester.chunk-age-jitter
    • -ingester.concurrent-flushes
    • -ingester.spread-flushes
    • -store.* except -store.engine and -store.max-query-length
    • -store.query-chunk-limit was deprecated and replaced by -querier.max-fetched-chunks-per-query
  • -deletes.*
  • -grpc-store.*
  • -flusher.wal-dir, -flusher.concurrent-flushes, -flusher.flush-op-timeout
  • [CHANGE] Remove support for alertmanager and ruler legacy store configuration. Before upgrading, you need to convert your configuration to use the alertmanager-storage and ruler-storage configuration on the version that you're already running, then upgrade.
