ASF GitHub Bot commented on KYLIN-5748: --------------------------------------- zznlime opened a new pull request, #2162: URL: https://github.com/apache/kylin/pull/2162 For an index build job, if all the new added indexes can be built from their existed parent index. No index was built from new created flat table. For this case, there won't be any data inconsistency across indexes. And there is no need to build a new flat table to serve the stage of index build by layer. So I think we can skip stage BUILD DICT and stage GENERATE FLAT TABLE for an index build job in condition that all new added indexes can be built from their existed parent index > Skip build flat table for index build job if all new created indexes can be > built from existed parent index > ----------------------------------------------------------------------------------------------------------- > > Key: KYLIN-5748 > URL: https://issues.apache.org/jira/browse/KYLIN-5748 > Project: Kylin > Issue Type: Improvement > Affects Versions: 5.0-beta > Reporter: Zhenning Zhang > Assignee: Zhenning Zhang > Priority: Major > > For an index build job, if all the new added indexes can be built from their > existed parent index.
