Job server on Go + python client

Job server provides a generic application framework to farm out work to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing. It support python 3, python2.7

Compile

go build -o jserver job_server/*.go

Run

> jserver

Arguments

• -log
• -couter
• -client localhost:8010
• -worker localhost:8011

Example of python worker

import jclient

def echo(data):
    return data

rpc = jclient.WorkerHandler('localhost', 8011)
rpc.add('echo', echo)  #  attach a method
rpc.serve()
rpc.close()

Example of python client

import jclient

rpc = jclient.ClientHandler('localhost', 8010)
result = rpc.call('echo', b'data')  # call a method
rpc.close()

Example of python asyncio worker

import asyncio
from jclient.async import WorkerAsyncHandler

@asyncio.coroutine
def ping(raw):
    yield from asyncio.sleep(1)
    return b'pong'

def echo(raw):
    return raw

@asyncio.coroutine
def worker(loop):
    rpc = WorkerAsyncHandler('localhost', 8011, loop=loop)
    rpc.add('ping', ping)
    rpc.add('echo', echo)
    yield from rpc.serve()

loop = asyncio.get_event_loop()
loop.run_until_complete(worker(loop))
loop.close()

Example of python asyncio client

import asyncio
from jclient.async import ClientAsyncHandler

@asyncio.coroutine
def run(loop):
    rpc = ClientAsyncHandler('localhost', 8010, loop=loop)

    result = yield from rpc.call('ping', b'data')
    print(result)

    rpc.close()

loop = asyncio.get_event_loop()
loop.run_until_complete(run(loop))
loop.close()
