> Instead of a single read(block) cache, if HBase can support creation of named read caches and use by tables it will help common scenarios like
> - Assigning a chunk of the cache to tables with data which are critical to performance so that they don’t get swapped out due to other less critical table data being read
> - To be able to guarantee a percentage of the cache to tenants in a multi tenant environment by assigning named caches to each tenant
