• [ENHANCEMENT] Use separate Cassandra clients and connections for reads and writes. cortexproject#2666
• [ENHANCEMENT] Add -cassandra.reconnect-interval to allow specifying the reconnect interval to a Cassandra server that has been marked DOWN by the gocql driver. Also change the default value of the reconnect interval from 60s to 1s. cortexproject#2687
• [ENHANCEMENT] Add -cassandra.convict-hosts-on-failure to allow disabling of host failure conviction on connection failures. cortexproject#2684
• [ENHANCEMENT] Use fork of gocql to export Prometheus metrics and GoKit logs. cortexproject#2684

v1.1.0-grafana-1 / 2020-05-27

• [FEATURE] TLS config options added for GRPC clients in Querier (Query-frontend client & Ingester client), Ruler, Store Gateway, as well as HTTP client in Config store client. cortexproject#2502

1.0.1-grafana-2 / 2020-05-07

0.7.0-grafana-1 / 2020-03-20

• [CHANGE] Don't support mixed time units anymore for duration. For example, 168h5m0s doesn't work anymore, please use just one unit (s|m|h|d|w|y). cortexproject#2252
• [CHANGE] Utilize separate protos for rule state and storage. Experimental ruler API will not be functional until the rollout is complete. cortexproject#2226
• [CHANGE] Frontend worker in querier now starts after all Querier module dependencies are started. This fixes issue where frontend worker started to send queries to querier before it was ready to serve them (mostly visible when using experimental blocks storage). cortexproject#2246
• [CHANGE] Lifecycler component now enters Failed state on errors, and doesn't exit the process. (Important if you're vendoring Cortex and use Lifecycler) cortexproject#2251
• [FEATURE] Added experimental storage API to the ruler service that is enabled when the -experimental.ruler.enable-api is set to true cortexproject#2269
  • -ruler.storage.type flag now allows s3,gcs, and azure values
  • -ruler.storage.(s3|gcs|azure) flags exist to allow the configuration of object clients set for rule storage
• [FEATURE] Flusher target to flush the WAL.
  • -flusher.wal-dir for the WAL directory to recover from.
  • -flusher.concurrent-flushes for number of concurrent flushes.
  • -flusher.flush-op-timeout is duration after which a flush should timeout.
• [ENHANCEMENT] Allow DNS discovery without using SRV records for memcached. cortexproject#2281
• [ENHANCEMENT] Better re-use of connections to DynamoDB and S3. cortexproject#2268
• [ENHANCEMENT] Experimental TSDB: Add support for local filesystem backend. cortexproject#2245
• [ENHANCEMENT] Experimental TSDB: Added memcached support for the TSDB index cache. cortexproject#2290
• [ENHANCEMENT] Allow 1w (where w denotes week) and 1y (where y denotes year) when setting table period and retention. cortexproject#2252
• [ENHANCEMENT] Added FIFO cache metrics for current number of entries and memory usage. cortexproject#2270
• [ENHANCEMENT] Output all config fields to /config API, including those with empty value. cortexproject#2209
• [BUGFIX] Fixed etcd client keepalive settings. cortexproject#2278
• [BUGFIX] Fixed bug in updating last element of FIFO cache. cortexproject#2270
• [BUGFIX] Register the metrics of the WAL. cortexproject#2295
