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. -- This message was sent by Atlassian JIRA (v6.2#6252)
