> This is designed to improve the coprocessor invocation in the client side.
> Currently the coprocessor invocation is to send a call to each region. If
> there’s one region server, and 100 regions are located in this server, each
> coprocessor invocation will send 100 calls, each call uses a single thread in
> the client side. The threads will run out soon when the coprocessor
> invocations are heavy.
> In this design, all the calls to the same region server will be grouped into
> one in a single coprocessor invocation. This call will be spread into each
> region in the server side.
