---------------------------------------
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.
