If= there=E2=80=99s one region server, and 100 regions are located in this ser= ver, each coprocessor invocation will send 100 calls, each call uses a sing= le thread in the client side. The threads will run out soon when the coproc= essor invocations are heavy.=20 > In this design, all the calls to the same region server will be grouped i= nto one in a single coprocessor invocation. This call will be spread into e= ach region in the server side. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
