mprpc is a lightweight `MessagePack RPC <https://github.com/msgpack-rpc/msgpack-rpc>`_ library. It enables you to easily build a distributed server-side system by writing a small amount of code. It is built on top of `gevent <http://www.gevent.org/>`_ and `MessagePack <http://msgpack.org/>`_.


Installation
------------

To install mprpc, simply:

.. code-block:: bash

$ pip install mprpc

Alternatively,

.. code-block:: bash

$ easy_install mprpc

Examples
--------

RPC server
^^^^^^^^^^

.. code-block:: python

from gevent.server import StreamServer
from mprpc import RPCServer

class SumServer(RPCServer):
def sum(self, x, y):
return x + y

server = StreamServer(('127.0.0.1', 6000), SumServer())
server.serve_forever()

RPC client
^^^^^^^^^^

.. code-block:: python

from mprpc import RPCClient

client = RPCClient('127.0.0.1', 6000)
print client.call('sum', 1, 2)


RPC client with connection pooling
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: python

import gsocketpool.pool
from mprpc import RPCPoolClient

client_pool = gsocketpool.pool.Pool(RPCPoolClient, dict(host='127.0.0.1', port=6000))

with client_pool.connection() as client:
print client.call('sum', 1, 2)


Performance
-----------

mprpc significantly outperforms the `official MessagePack RPC <https://github.com/msgpack-rpc/msgpack-rpc-python>`_ (**1.8x** faster), which is built using `Facebook's Tornado <http://www.tornadoweb.org/en/stable/>`_ and `MessagePack <http://msgpack.org/>`_, and `ZeroRPC <http://zerorpc.dotcloud.com/>`_ (**14x** faster), which is built using `ZeroMQ <http://zeromq.org/>`_ and `MessagePack <http://msgpack.org/>`_.
