Attach memcached as secondary block cache to regionserver
---------------------------------------------------------

                 Key: HBASE-4018
                 URL: https://issues.apache.org/jira/browse/HBASE-4018
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Li Pi
            Assignee: Li Pi


Currently, block caches are limited by heap size, which is limited by garbage collection times
in Java.

We can get around this by using memcached w/JNI as a secondary block cache. This should be
faster than the linux file system's caching, and allow us to very quickly gain access to a
high quality slab allocated cache.
