Hi, Is it possible to disable automatic cube enabling after a building process? For example, this could be useful if we need to create a new version of a cube but we do not want it to be consulted until new cube has been properly tested. Regards, Roberto Tardío Olmos Senior Big Data & Bus

Hi Kumar, “Then Cube2 will be sufficient to get all query. Why do we need to combine?” If you combine Cube 1 and Cube 2 using a Hybrid Model, queries that contains common columns (dimensions or measures) will be routed to hybrid cube, thus joining data from Cube 1 and Cube 2. I.e. This can b

Hello, What is your Apache Kylin version? In latest versions, I don’t think the job with error status can be dropped directly before discarding it. At this moment, you may need to download, edit to remove this segment and then upload your metadata, or start over with cloning the original cube.
