--------------------------------------

             Summary: HFileBlock backed by Array of ByteBuffers
                 Key: HBASE-12213
                 URL: https://issues.apache.org/jira/browse/HBASE-12213
             Project: HBase
          Issue Type: Sub-task
            Reporter: Anoop Sam John
            Assignee: Anoop Sam John


In L2 cache (offheap) an HFile block might have been cached into multiple chunks of buffers.
If HFileBlock need single BB, we will end up in recreation of bigger BB and copying. Instead
we can make HFileBlock to serve data from an array of BBs.
