             Summary: Reduce memory usage for building global dict
                 Key: KYLIN-2266
                 URL: https://issues.apache.org/jira/browse/KYLIN-2266
             Project: Kylin
          Issue Type: Improvement
    Affects Versions: v1.6.0
            Reporter: kangkaisen
            Assignee: kangkaisen


Because the input for building global dict is sequential，so we could set max 
cache size to 1 to reduce the  memory usage.

Although we also could set `kylin.dict.append.cache.size` to 1 to reduce the  
memory usage, most of users don't know this config.
