increase can make your code lighter and faster, and strongly typed mappings can check for Errors.Don't think You're done Here. There is also a faster library, but now only supports proto2, called pyrobuf library. based on the CPython implementation, according to the author, he is 2-4 times faster than C + + backend for Python. This because I installed a half-day not installed, it seems that the configuration of the CPython library a little bit of a problem, if you have faster requirements for

In Ruby and Rails developers, the service-oriented (service-oriented) architecture has a well-deserved reputation as a powerful way to mitigate the vicious growth of program size and to extract concerns in a large number of applications. These new, compact services typically continue to use rails or Sinatra and use JSON to communicate over HTTP. Although JSON as a data interchange format, there are many adv

By walking through creating a simple example appli

by the Protocol message class is reflection (reflection). You do not need to write code for a particular message type, you can iterate through the fields of a message and manipulate their values. A useful way to use reflection is to convert protocol messages to and from other encodings, such as XML or JSON. A more advanced usage of reflection might be to find ou

Protocol buffers is a data description language developed by Google, similar to XML that can serialize structured data for data storage and communication protocols. At this stage of support Hold three programming languages, such as C + +, JAVA, Python. It is a binary format, much faster than using XML for data exchange. It can be used in data communication between distributed applications or in heterogeneou

magnitude faster than XML. Google Documents said that the size of the Protocol buffers file is 3-10 times smaller than that of comparable XML files, and the resolution speed is 20-times faster. Free files released by Google include Java, Python, and C ++Programming LanguageSource code of the Protocol buffers compil

optional field does not exist in the old message. You must explicitly use the has _ method to determine whether it is set or. the default value is provided in the form of [default = value] In the proto file. If the default value is not specified, values are assigned based on the default type. For the string type, the default value is a null string. For bool, the default value is false. For numeric type, the default value is 0.9. Advanced usage The application of

Http://martin.kleppmann.com/2012/12/05/schema-evolution-in-avro-protocol-buffers-thrift.html When you want to store data, such as objects or other types of data, to a file or transmit data over the network, you need to face the serialization problem.For serialization, each language provides corresponding packages, such as Java serialization, Ruby's marshal, or Python's pickle. Everything is fine, but if you

Protocol buffers is a language-neutral serialization format for ideal structured data. You can consider XML or JSON, but the Protocol buffer is lighter and smaller. This format is widely used for data exchange between different Google systems. Due to its optimal performance of structured data,

Recently, we need to save some structured data. The general idea is to select XML. Define a schema, and then find a neat XML library (think tinyxml/tinyxml ++ is quite good), even if the problem is solved.

Google is Google, and even if it is pushed out, it can make p
