      Description

      from https://issues.apache.org/jira/browse/KYLIN-671, https://issues.apache.org/jira/browse/KYLIN-836 we introduced a storage level cache to take care of dynamic storages like Inverted Index (dynamic storage keeps refreshing all the time)

      however the II approach is not very popular since invented. And a storage level cache is too heavy&complex and problematic(see https://issues.apache.org/jira/browse/KYLIN-1522) for the more most commonly used "static" cube storage engine. Thus I'd suggest to go back to before KYLIN-671 and simply use a controller level cache.
