When upgrading the frontend, cache entries will be discarded and re-created with the new protobuf schema. #1734 -* [CHANGE] Remove direct DB/API access from the ruler +* [CHANGE] Removed direct DB/API access from the ruler. `-ruler.configs.url` has been now deprecated. #1579 * [CHANGE] Removed `Delta` encoding. Any old chunks with `Delta` encoding cannot be read anymore. If `ingester.chunk-encoding` is set to `Delta` the ingester will fail to start. #1706 * [CHANGE] Setting `-ingester.max-transfer-retries` to 0 now disables hand-over when ingester is shutting down. Previously, zero meant infinite number of attempts. #1771 * [CHANGE] `dynamo` has been removed as a valid storage name to make it consistent for all components. `aws` and `aws-dynamo` remain as valid storage names. +* [CHANGE/FEATURE] The frontend split and cache intervals can now be configured using the respective flag `--querier.split-queries-by-interval` and `--frontend.cache-split-interval`. + * If `--querier.split-queries-by-interval` is not provided request splitting is disabled by default. + * __`--querier.split-queries-by-day` is still accepted for backward compatibility but has been deprecated.

Components can gossip about tokens and ingester states, instead of using Consul or Etcd. #1721 +* [FEATURE] EXPERIMENTAL: Use TSDB in the ingesters & flush blocks to S3/GCS ala Thanos. This will let us use an Object Store more efficiently and reduce costs. #1695 * [FEATURE] Allow Query Frontend to log slow queries with `frontend.log-queries-longer-than`. #1744 -* [FEATURE] The frontend split and cache intervals can now be configured using the respective flag `--querier.split-queries-by-interval` and `--frontend.cache-split-interval`. - * If `--querier.split-queries-by-interval` is not provided request splitting is disabled by default. - * __`--querier.split-queries-by-day` is still accepted for backward compatibility but has been deprecated.

Rate limiting is disabled by default. New flags added: `--consul.watch-rate-limit`, and `--consul.watch-burst-size`. #1708 * [ENHANCEMENT] Added jitter to HA deduping heartbeats, configure using `distributor.ha-tracker.update-timeout-jitter-max` #1534 -* [ENHANCEMENT] Allocation improvements in adding samples to Chunk. #1706 -* [ENHANCEMENT] Consul client now follows recommended practices for blocking queries wrt returned Index value. #1708 -* [ENHANCEMENT] Consul client can optionally rate-limit itself during Watch (used e.g. by ring watchers) and WatchPrefix (used by HA feature) operations.
