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

             Summary: Improve network utilization for scanning RPC requests by preloading
the next set of results on the server
                 Key: HBASE-12994
                 URL: https://issues.apache.org/jira/browse/HBASE-12994
             Project: HBase
          Issue Type: Improvement
            Reporter: Jonathan Lawlor


As [~lhofhansl] has called out in HBASE-11544, RPC is inefficient when scanning. The way it
currently works is the client requests a buffer worth of results and works through that buffer.
Once that buffer of results is exhausted, the client realizes it has run out of results and
then requests the next buffer. This could be improved by beginning to load the next buffer
while the client is working through the current buffer of results.
