msgpack

前言 如果有业务需要将一个数据塞进队列由另一端接收,我们就需要考虑到数据的大小,因为这跟队列的效率和稳定性正相关,如果你希望能对这部分数据进行一定的压缩,并且提高解压缩的效率时,希望你能想到 msgpack 正文 性能对比 效率 这里先放出测试的数据 我们将网页源代码与其他数据组成dict,使用JSON和msgpack进行转换,每次转换都为dict转换目标格式再转换回来 循环1000次打印耗费时间 代码如下 结果如下 大小 我们数据不变,修改测试代码为下图,意为打印转换后的长度和转换后的数据 结果为 使用 是不是对这种效果满意,那么我们开始使用 安装 pip install umsgpack 转换 import umsgpack umsgpack可方便地将大部分数据格式转换,需要注意的是datetime类型等Python独有的无法正常转换(跟json限制差不多) packd = umsgpack.packb(t) umsgpack.packb可将数据转换为bytes类型的数据 res = umsgpack.unpackb(packd) umsgpack.unpackb将转换后的bytes数据转换为Python使用的数据格式 来源： https://www.cnblogs.com/chnmig/p/12012383.html

I have a C# reply server that can pack an object and send it to a requester C# client. Can I do the same thing, but with a C# reply server communicating with a C++ requester client? Here's an example of my C# reply server: using System; using System.Text; using ZMQ; using MsgPack; namespace zmqMpRep { public class Weather { public int zipcode; public int temperature; public int humidity; } public class zmqMpRep { public static void Main(string[] args) { Socket replier = new Socket( SocketType.REP ); replier.Bind( "tcp://127.0.0.1:9293" ); while( true ) { Weather weather = new Weather { zipcode

I'm having a problem storing a MessagePacked hash in Redis. I've pasted a test case below. When pulling out the packed data from Redis and unpacking it, the hash is slightly corrupted. This appears to happen when the hash values are beyond a certain length, although I can't say that for sure. I'm using Redis 2.4.17 (default config), Ruby 1.9.3p194, MessagePack 0.4.7, and the Redis gem 3.0.2. The same problem happens using node, so I'm assuming the problem is within MessagePack or Redis. Any ideas? require 'redis' require 'msgpack' class Test def self.run(url) redis = Redis.new data = {'number'

I wonder if any of the high performance serialization libraries (like Google protocol buffers) support sum types . Sum types are tagged unions, basically the ability to say that something is either A, B, or C. Sum types are used in languages such as Haskell and ML which support Algebraic Data Types If by "like Google protocol buffers" you mean ability to generate code for multiple languages then probably such thing doesn't exist. Emulating sum types in languages which don't support them is awkward at best (try to pattern match on boost:variant for example). So it makes sense to leave them out
