> Currently there is a config "kylin.cube.max-building-segments" (default be 10) set the max. jobs for a cube.
> In a frequently build case, that is possible that have 10 segments being built concurrently. Then there is no room for the merge jobs. If the merge job is blocked, more segments will be accumulated, and then impact on the query performance.
>  
> So I suggest to disable the checking for merge jobs.
