I shall port this patch to apache-trunk soon.
(Not sure why the reviews.facebook.net does not work out with jira this time.)
> Optimize the HBaseServer to deserialize the data for each ipc connection in
> parallel

>
> Currently HBaseServer is running with a single listener thread, which is
> responsible for accepting the connection, reading the data from network
> channel, deserializing the data into writable objects and handover to the IPC
> handler threads.
> When there are multiple hbase clients connecting to the region server
> (HBaseServer) and reading/writing a large set of data, the listener and the
> respond thread will be performance bottleneck.
> So the solution is to deserialize the data for each ipc connection in
> parallel for HBaseServer
> BTW, it is also one of the reasons that the parallel scanning from multiple
> clients is far slower than single client case.
