    Description

      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
