> There are many tables on our cluster,  only some of them need to be read online.  
> We could improve the performance of read by cache,  but we need some metrics for it at
table level. There are a few we can collect: BlockCacheCount, BlockCacheSize, BlockCacheHitCount,
BlockCacheMissCount, BlockCacheHitPercent
