-------------------------------------
Hi hongbin. I was not referring to result cache. I was referring to the
dimension snapshots which are kept in memory. We can put in a lru cache for the
snapshots which has to be in memory ? There might be cases where certain
dimensions are not queried as often, but still its in memory
> LRU cache for in memory dimensions

> Project: Kylin
> Issue Type: Improvement
> Components: Query Engine
> Affects Versions: v1.2, v1.5.2
> Reporter: Abhilash L L
> Assignee: liyang
>
> The dimensions are kept in memory to fill up the result set.
> Now as and when more cubes are created, all the dimensions keep accumulating
> in the memory
> This means tomcat memory requirements always keep increasing
> It would help if less frequently used dimensions are swapped out to keep
> memory in check.
> We can have a Cache Manager which gets to decide which dimensions are kept in
> memory and brings in as and when its required. The size of the cache should
> be tuneable.
