DescriptionLocation
Producer
• Batch-size가 1일 경우 상당한 퍼포먼스 문제
• 위의 테스트는 batch-size 200으로 처리(200개 메시지 들어올 경우 flush)
Consumer
• Multi consumer 일 경우라 하더라도 하나의 파티션에 대해 하나의 consumer만 처리
• Consumer pool이 하나의 디스크로 인하여 의미가 없음
• Consumer pool

ØMQ Overview
Features
Intelligent socket library for messaging
Many kinds of connection patterns
Multiplatform, multi-language (30+)
Fast (8M msg/sec, 30usec latency)
Small (20K lines of C++ code)
Open source LGPL (large community)
[Basic] [Forwarding]
[Pub/Sub] [Broadcast]

DescriptionSolution
RabbitMQ
• Stable send/receive process
• Can use AMQP(High performance)
• Similar producer/consumer speed
• Support runtime queue create/delete(very flexible)
Producer/Consumer Simultaneously; 2K and 10K message

Commercial Support SpringSource(VMWare) iMatrix
Monitoring Many plugin for monitoring, web based GUI Implementation needed
Remarks
• Powerful web based monitoring
• AMQP1) Support
• Dynamic topic management
• Easy of Development
• High throughput/Low latency
• Auto reconnect among peer
• Run on arbitrary platforms (Windows,
Android)
1) AMQP(Asynchronous Message Queuing Protocol) : Supported by Microsoft, Red Hat, VMware, Cisco, Novell, SoftwareAG, etc.
Ø MQ is very lightweight and fast, but we’ll have to implement most of features ourselves
Flexibility, reliability, and easy to use are important in this project, not performance

Client/Server
import org.zeromq.ZMQ;
public class hwclient {
public static void main (String[] args){
ZMQ.Context context = ZMQ.context (1);
ZMQ.Socket socket = context.socket (ZMQ.REQ);
socket.connect ("tcp://localhost:5555");
socket.send ("Hello", 0);
System.out.println (socket.recv(0));
}
}
import org.zeromq.ZMQ;
public class hwserver {
public static void main (String[] args) {
ZMQ.Context context = ZMQ.context(1);
ZMQ.Socket socket = context.socket(ZMQ.REP);
socket.bind ("tcp://*:5555");
while (true) {
byte [] request = socket.recv (0);
socket.send("World", 0);
}
}
}

Queue Load Balancing
import zmq
context = zmq.Context()
socket = context.socket(zmq.REQ)
socket.connect("tcp://127.0.0.1:5000")
for i in range(10):
msg = "msg %s" % i
socket.send(msg)
print "Sending", msg
msg_in = socket.recv()
import zmq
socket = context.socket(zmq.REP)
socket.bind("tcp://127.0.0.1:5000")
while True:
msg = socket.recv()
print "Got", msg
socket.send(msg)
import zmq
socket = context.socket(zmq.REP)
socket.bind("tcp://127.0.0.1:6000")
while True:
msg = socket.recv()
print "Got", msg
socket.send(msg)
Each server will be received five messages equivalently

16
Broadcast - Pub/Sub
import zmq
from random import choice
socket = context.socket(zmq.PUB)
socket.bind("tcp://127.0.0.1:5000")
countries = ['netherlands','brazil','germany','portugal']
events = ['yellow card', 'red card', 'goal', 'corner', 'foul']
while True:
msg = choice( countries ) +" "+ choice( events )
print "->",msg
socket.send( msg )
import zmq
socket = context.socket(zmq.SUB)
socket.setsockopt(zmq.SUBSCRIBE, "netherlands")
socket.setsockopt(zmq.SUBSCRIBE, "germany")
while True:
print socket.recv()
Subscriber will be received only “netherlands” and “germany”
