Difference between Apache Thrift and ZeroMQ

由 谁都会走 提交于 2019-12-20 08:48:37
问题 I understand that Apache Thrift and ZeroMQ are softwares belonging to different categories, and it is not easy to do a comparison since it is an apple to orange comparison. But I don't know why they belong to different categories. Aren't they both used to pass data between different services, which may or may not be written in different languages? When should I use Thrift and when should I use a message queue? 回答1: They belong to different categories primarily because they are targetted at

How to implement distributed processing [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I have requests coming in for different samples (s1, s2, ..) that need to be processed in a linear fashion (i.e. only one say s1-request at the time can be processed). I have N-number of worker services that can process given requests. How can I implement rpc-queue pattern so that

How could I set hwm in the push/pull pattern of zmq?

由 好久不见. 提交于 2019-12-20 05:31:25
问题 I have found a similar question, ZeroMQ: HWM on PUSH does not work, but it couldn't solve my problem. I want to control the number of messages that the push socket queues, but it doesn't work and still queues 1000 messages. So I want to know how to set the hwm of the push socket. Thanks in advance. My environment is: libzmq 4.0.4, pyzmq 14.1.0, python 3.3 Here's my code: server.py #!/usr/bin/env python3 # -*- coding: utf-8 -*- import random import zmq class TestPush(object): def __init__(self

下载 ZeroMQ：http://download.zeromq.org/ 如需 zmq.hpp 可从这里下载：https://github.com/zeromq/cppzmq/archive/master.zip 也可以从github上搜索libzmq下载，但是编译跟本次不同 编译 tar -xvf zeromq-4.1.2.tar.gz ./configure --prefix= pwd /develop/ --with-libsodium=no make && make install 如果需要libsodium库的支持，请将上述的no去掉，否则会报错 No package ‘libsodium’ found 其他，–with-libsodium=no 或者 --without-libsodium 命令达到的效果相同 来源： CSDN 作者： huangjiazhi_ 链接： https://blog.csdn.net/huangjiazhi_/article/details/103614985

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Fixing the World How to explain ZeroMQ? Some of us start by saying all the wonderful things it does. It's sockets on steroids. It's like mailboxes with routing. It's fast! Others try to share their moment of enlightenment, that zap-pow-kaboom satori paradigm-shift moment when it all became obvious. Things just become simpler. Complexity goes away. It opens the mind. Others try to explain by comparison. It's smaller, simpler, but still looks familiar. Personally, I like to remember why we made ZeroMQ at all, because that's most likely where you, the reader,

One ZeroMQ socket per thread or per call?

由 你说的曾经没有我的故事 提交于 2019-12-19 04:25:47
问题 As we all know, a ZeroMQ socket shall not be shared among application threads. context_t instances however can. I have a multi-threaded-application and I'd like to have each thread exchange messages from time to time with a REQ/REP -socket counterparty ( event, exceptions and the like ), depending on what they are doing ( they are doing non-ZeroMQ-stuff ). To send messages to my REQ/REP -socket I use the following function ( a half-C++ half-pseudo-code ): sendMessage: bool sendMessage(std:

Send user ID from browser to websocket server while opening connection

由 我只是一个虾纸丫 提交于 2019-12-18 17:29:44
问题 Before asking this question, I did my best by reading severel questions on SO (tagged Ratchet and dealing with similar issues but to no avail. I even asked a question which received no attention and I therefore deleted it to write another one (that hopefully is more clear). My final goal is to build a one-to-one private chat application using Ratchet. Everything is working fine except that I can't send message to a specific user. Every logged in user connects to the websocket server while

zmq send with NOBLOCK raise Resource temporarily unavailable

由 廉价感情. 提交于 2019-12-18 12:38:35
问题 This code will raise Resource temporarily unavailable when call with NOBLOCK: context = zmq.Context() sender = context.socket(zmq.PUSH) sender.bind('tcp://*:15556') sender.send('KeEpAliv', zmq.NOBLOCK) # this line will throw exception #sender.send('KeEpAliv') # this line will ok After read the docs, I found no hints for this. but docs for recv explained this flag. 回答1: Python wrappers raise zmq.error.Again if the underlying C API returns EAGAIN . Now, you should follow to zmq_send

zmq vs redis for pub-sub pattern

由 微笑、不失礼 提交于 2019-12-18 10:29:34
问题 redis supports pub-sub zmq also supports pub-sub via a message broker What would be the architectural pros\cons for choosing between them? I'm aiming at points which are beyond the obvious use-case specific performance benchmarking that should be done (here's a nice example). Assume use of a high-level language such as Python. 回答1: I have worked with both ZeroMQ and Redis with python. I would say ZeroMQ is more robust, it offers real simple load balancing and also more than pub-sub, like
