> Project: HBase
> Issue Type: Improvement
> Components: Client, Performance

>
> 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
> on the server while the client is working through the current buffer of
> results.
