> 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.
