Wang Cheng updated KYLIN-1788: ------------------------------ Attachment: 0001-kylin-1788-enable-arbitrary-mandatory-size.patch > Allow arbitrary number of mandatory dimensions in one aggregation group > ------------------------------------------------------------------------ > > Key: KYLIN-1788 > URL: https://issues.apache.org/jira/browse/KYLIN-1788 > Project: Kylin > Issue Type: Bug > Affects Versions: v1.5.2 > Reporter: hongbin ma > Assignee: hongbin ma > Attachments: 0001-kylin-1788-enable-arbitrary-mandatory-size.patch > > > To prevent one aggregation group containing too many combinations we apply a > check > {code:java} > if (mandatoryDims.size() + normalDimSize + hierarchySize + jointSize > > maxSize) { > context.addResult(ResultLevel.ERROR, "Aggregation group " + > index + " has too many dimensions"); > continue; > } > {code} > however the formular fails to take into account the case where there're many > mandatory dimensions. For example, if we have 50 dimensions in a cube and we > only need the base cuboid, then what we want is a single aggregation group > containing all the dimensions, each of them being a mandatory. > since mandatory dimensions are more "encouraged", I suggest to remove > counting mandatory dimensions in the formula. the revised code will be: > {code:java} > if (normalDimSize + hierarchySize + jointSize > maxSize) { > context.addResult(ResultLevel.ERROR, "Aggregation group " + > index + " has too many dimensions"); > continue; > } > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
