             Summary: cache parent datasource to accelerate next layer's cuboid building
                 Key: KYLIN-4903
                 URL: https://issues.apache.org/jira/browse/KYLIN-4903
             Project: Kylin
          Issue Type: Improvement
            Reporter: ShengJun Zheng


Parent datasource is not cached in next layer's cuboid building, causing repeated HDFS files read. Cacheing parent datasource in memory will in enhance 20~30% build performance in our case.
