0.2.0 / 2019-09-05

This release has several exciting features, the most notable of them being setting -ingester.spread-flushes to potentially reduce your storage space by upto 50%.

• [CHANGE] Flags changed due to changes upstream in Prometheus Alertmanager #929:
  • alertmanager.mesh.listen-address is now cluster.listen-address
  • alertmanager.mesh.peer.host and alertmanager.mesh.peer.service can be replaced by cluster.peer
  • alertmanager.mesh.hardware-address, alertmanager.mesh.nickname, alertmanager.mesh.password, and alertmanager.mesh.peer.refresh-interval all disappear.
• [CHANGE] --claim-on-rollout flag deprecated; feature is now always on #1566
• [CHANGE] Retention period must now be a multiple of periodic table duration #1564
• [CHANGE] The value for the name label for the chunks memcache in all cortex_cache_ metrics is now chunksmemcache (before it was memcache) #1569
• [FEATURE] Makes the ingester flush each timeseries at a specific point in the max-chunk-age cycle with -ingester.spread-flushes. This means multiple replicas of a chunk are very likely to contain the same contents which cuts chunk storage space by up to 66%. #1578
• [FEATURE] Make minimum number of chunk samples configurable per user #1620
• [FEATURE] Honor HTTPS for custom S3 URLs #1603
• [FEATURE] You can now point the query-frontend at a normal Prometheus for parallelisation and caching #1441
• [FEATURE] You can now specify http_config on alert receivers #929
• [FEATURE] Add option to use jump hashing to load balance requests to memcached #1554
• [FEATURE] Add status page for HA tracker to distributors #1546
• [FEATURE] The distributor ring page is now easier to read with alternate rows grayed out #1621
