Subject [jira] [Commented] (SOLR-12208) Don't use "INDEX.sizeInBytes" as a tag name in policy calculations
Date Fri, 07 Sep 2018 11:35:00 GMT


Andrzej Bialecki  commented on SOLR-12208:

No - all of these doc references are still correct. This issue addresses how this metric name
was used internally for autoscaling policy calculations.

> CORE_IDX and FREEDISK ConditionType reuse this metric name, but they assume the values
are expressed in gigabytes. This alone is confusing considering the name of the metric.
> Additionally, it causes conflicts in the simulation framework that would require substantial
changes to resolve (ReplicaInfo-s in SimClusterStateProvider keep metric values in their variables,
expressed in original units - but then the Policy assumes it can put the values expressed
in GB under the same key... hilarity ensues).
