Biju Nair commented on HBASE-18138:
-----------------------------------
The current {{LruBlockCache/BucketCache}} implementations can be modified to
support named caches with the current state to be cache named {{default}}.
Attached has some quick changes for {{LruBlockCache}} made to see how complex
the changes would be.

> 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
