[jira] [Created] (KYLIN-1526) Move query cache back to query controller level

hongbin ma created KYLIN-1526:
---------------------------------

             Summary: Move query cache back to query controller level
                 Key: KYLIN-1526
                 URL: https://issues.apache.org/jira/browse/KYLIN-1526
             Project: Kylin
          Issue Type: Improvement
            Reporter: hongbin ma
            Assignee: hongbin ma


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.
