Subject [jira] [Created] (HBASE-18138) HBase named read caches
Date Wed, 31 May 2017 04:08:05 GMT
Biju Nair created HBASE-18138:

             Summary: HBase named read caches
                 Key: HBASE-18138
                 URL: https://issues.apache.org/jira/browse/HBASE-18138
             Project: HBase
          Issue Type: New Feature
          Components: BlockCache, BucketCache
            Reporter: Biju Nair

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
