> Currently we already have a metrics in name of
> {{blockCacheExpressHitPercent}} to indicate the cache hit ratio. However,
> since meta block is small and often cached in memory with a high hit ratio,
> this "mixed" metrics could not show the real data block hit ratio which is
> more concerned.
> We propose to add two new metrics to show meta and data block cache hit ratio
> separately, while reserving the old metrics for backward compatibility.
