[jira] [Created] (KYLIN-2065) kylin result cache improvement

fengYu created KYLIN-2065:
-----------------------------

             Summary: kylin result cache improvement
                 Key: KYLIN-2065
                 URL: https://issues.apache.org/jira/browse/KYLIN-2065
             Project: Kylin
          Issue Type: Improvement
            Reporter: fengYu
            Assignee: fengYu


data stored in kylin(hbase) is rarely modified, except some one refresh a segment, I think a result cache is useful, kylin support in-memory ehcache, but it is limited and can not share between query nodes, we develop a cache solution which  store in hbase and expire based on cube last-modify-time or segment last-modify-time.

I will arrange the patch on 1.5.4 which will upload later.
