Parallel Pipeline模式：

由三部分组成，push进行数据推送，work进行数据缓存，pull进行数据竞争获取处理。区别于Publish-Subscribe存在一个数据缓存和处理负载。

当连接被断开，数据不会丢失，重连后数据继续发送到对端

client

import sys
import zmq
 
context = zmq.Context()
socket = context.socket(zmq.PUSH)
socket.bind('tcp://*:5557')
 
while True:
    data = input("input your data:")
    if data == 'q':
        sys.exit()
    print(data)
    socket.send(data.encode('utf-8'))

work

# -*-coding:utf-8 -*-
import zmq
 
context = zmq.Context()

recive.connect('tcp://127.0.0.1:5557')

sender.bind('tcp://127.0.0.1:5558')
 
while True:
    data = recive.recv()
    print(data)
    sender.send(data)

server
