aiorpc is a lightweight asynchronous 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 asyncio and MessagePack.
Note aiorpc is under development, should not be considered to have a stable API.
To install aiorpc, simply:
$ pip install aiorpc
from aiorpc import RPCServer
import asyncio
import uvloop
def echo(msg):
return msg
rpc_server = RPCServer()
loop = uvloop.new_event_loop()
asyncio.set_event_loop(loop)
rpc_server.register("echo", echo)
coro = asyncio.start_server(rpc_server.serve, '127.0.0.1', 6000, loop=loop)
server = loop.run_until_complete(coro)
try:
loop.run_forever()
except KeyboardInterrupt:
server.close()
loop.run_until_complete(server.wait_closed())
from aiorpc import RPCClient
import asyncio
import uvloop
async def do(cli):
ret = await client.call('echo', 'message')
print("{}\n".format(ret))
loop = uvloop.new_event_loop()
asyncio.set_event_loop(loop)
client = RPCClient('127.0.0.1', 6000)
loop.run_until_complete(do(client))
client.close()
aiorpc client can also be used as an async context manager:
async def do():
async with RPCClient('127.0.0.1', 6000) as client:
ret = await client.call('echo', 'message')
print("{}\n".format(ret))
aiorpc with uvloop significantly outperforms ZeroRPC (6x faster), which is built using ZeroMQ and MessagePack and slightly underperforms official MessagePack RPC (0.7x slower), which is built using Facebook's Tornado and MessagePack.
