> Metastore currently uses black/white list to specify patterns of tables to
> load into the cache. Cache is loaded in one shot "prewarm", and updated by a
> background thread. This is not a very efficient design.
> In this feature, we try to enhance the cache for Tables with LRU to improve
> cache utilization.
