Billy Liu commented on KYLIN-2965: ---------------------------------- Interesting found. +1 > RealizationChooser cost calculation logic different with CubeInstance > --------------------------------------------------------------------- > > Key: KYLIN-2965 > URL: https://issues.apache.org/jira/browse/KYLIN-2965 > Project: Kylin > Issue Type: Improvement > Components: Query Engine > Reporter: Ma Gang > Assignee: Ma Gang > Priority: Minor > Attachments: kylin-2965.patch > > > In RealizationChooser.RealizationCost, it uses cube's all > dimensions(including all derived columns) to calculate the cost, but in > CubeInstance, it use row key column count. Think it is a bug, should not > include the derived column number to calculate cost -- This message was sent by Atlassian JIRA (v6.4.14#64029)
