Subject [jira] [Created] (HBASE-4027) Enable direct byte buffers LruBlockCache

Enable direct byte buffers LruBlockCache

                 Key: HBASE-4027
                 URL: https://issues.apache.org/jira/browse/HBASE-4027
             Project: HBase
          Issue Type: Improvement
            Reporter: Jason Rutherglen
            Priority: Minor

Java offers the creation of direct byte buffers which are allocated outside of the heap.

They need to be manually free'd, which can be accomplished using an documented {{clean}} method.

The feature will be optional.  After implementing, we can benchmark for differences in speed
and garbage collection observances.
