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

             Summary: Explore object pooling of SeekerState
                 Key: HBASE-16703
                 URL: https://issues.apache.org/jira/browse/HBASE-16703
             Project: HBase
          Issue Type: Task
            Reporter: Andrew Purtell


In read workloads 35% of the allocation pressure produced by servicing RPC requests comes from SeekerState.<init> of the DataBlockEncoder implementation currently in use, where we allocate two byte arrays of INITIAL_KEY_BUFFER_SIZE in length. There's an opportunity for object pooling of SeekerState here. Subsequent code checks if those byte arrays are sized sufficiently to handle incoming data to copy. The arrays will be resized if needed.
