             Summary: Reuse global dictionary from other cube
                 Key: KYLIN-4335
                 URL: https://issues.apache.org/jira/browse/KYLIN-4335
             Project: Kylin
          Issue Type: New Feature
          Components: Job Engine
    Affects Versions: Future
            Reporter: wangxiaojing
            Assignee: wangxiaojing


At present, global dictionary can reuse other columns in the same cube, but 
cannot reuse the dictionaries of other cubes in the cluster.
It is suggested that not only the global dictionaries of the same cube can be 
reused, but also the global dictionaries of other cubes can be reused, which 
can greatly reduce the build time of dictionaries and avoid the repeated build 
of dictionaries.
