hongbin ma commented on KYLIN-1146:
-----------------------------------
the key part is now replaced by sql digest's hashcode, this approach is not
perfect but it reduced the object number in key.
for the value part, it's naturally a collection of objects, can't fix it unless
we decide to store it as a serialized byte array form, and deserialize it upon
every read operation
> reduce the number of objects put into ehcache

> echcache will give warning if the K/V has lots of objects, maybe we should
> compact the K/V into just 2 objects before putting in
