zeronimo 0.1.1

RPC between distributed workers

A distributed RPC solution based on ØMQ and gevent. Follow the features:

• A worker can return, yield, raise any picklable object to the remote customer.

• A customer can invoke to any remote worker in the worker cluster.

• A customer can invoke to all remote workers in the worker cluster.

Example

Server-side

The address is 192.168.0.41. The worker will listen at 24600.

import zmq.green as zmq
import zeronimo

class Application(object):

    def rycbar123(self):
        for word in 'run, you clever boy; and remember.'.split():
            yield word

ctx = zmq.Context()
worker_sock = ctx.socket(zmq.PULL)
worker_sock.bind('tcp://*:24600')

worker = zeronimo.Worker(Application(), [worker_sock])
worker.run()

Client-side

The address is 192.168.0.42. The reply collector will listen at 24601.

import zmq.green as zmq
import zeronimo

ctx = zmq.Context()

collector_sock = ctx.socket(zmq.PULL)
collector_sock.bind('tcp://*:24601)
collector = zeronimo.Collector(collector_sock, 'tcp://192.168.0.42:24601')

customer_sock = ctx.socket(zmq.PUSH)
customer_sock.connect('tcp://192.168.0.41:24600')
customer = zeronimo.Customer(customer_sock, collector)

for line in customer.rycbar123():
    print line
