A lightweight Messagepack RPC using Python gevent
Project description
mprpc is a lightweight MessagePack 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 and MessagePack.
Installation
To install mprpc, simply:
$ pip install mprpcAlternatively,
$ easy_install mprpcExamples
RPC server
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
from mprpc import RPCClient
client = RPCClient('127.0.0.1', 6000)
client.open()
print client.call('sum', 1, 2)RPC client with connection pooling using gsocketpool
import gsocketpool.pool
from mprpc import RPCClient
client_pool = gsocketpool.pool.Pool(RPCClient, 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 (1.8x faster), which is built using Facebook’s Tornado and MessagePack, and ZeroRPC (14x faster), which is built using ZeroMQ and MessagePack.
