Learning Apache Thrift

Overview of this book

With modern software systems being increasingly complex, providing a scalable communication architecture for applications in different languages is tedious. The Apache Thrift framework is the solution to this problem! It helps build efficient and easy-to-maintain services and offers a plethora of options matching your application type by supporting several popular programming languages, including C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, OCaml, and Delphi. This book will help you set aside the basics of service-oriented systems through your first Apache Thrift-powered app. Then, progressing to more complex examples, it will provide you with tips for running large-scale applications in production environments. You will learn how to assess when Apache Thrift is the best tool to be used. To start with, you will run a simple example application, learning the framework's structure along the way; you will quickly advance to more complex systems that will help you solve various real-life problems. Moreover, you will be able to add a communication layer to every application written in one of the popular programming languages, with support for various data types and error handling. Further, you will learn how pre-eminent companies use Apache Thrift in their popular applications. This book is a great starting point if you want to use one of the best tools available to develop cross-language applications in service-oriented architectures.

Generating and Running Code in Different Languages

Ruby


Ruby is another very popular programming language used not only for web applications (that is, in the Ruby on Rails framework), but also for general scripting.

Generating the code

Apache Thrift's compiler has a limited number of special options for Ruby; there are only two. Run the following command to see them:

$ thrift --help 

Look for the information about Ruby generators:

  rb (Ruby):
    rubygems:        Add a "require 'rubygems'" line to the top of each generated file.
    namespaced:      Generate files in idiomatic namespaced directories.

Let's explain both of them:

  • rubygems: As the description states, it just adds the require 'rubygems' line on top of each file that is generated by the compiler.

  • namespaced: The files that are generated are put in the directories with the names of the namespaces which you selected.

If you need both options, you can combine them:

$ thrift --gen rb:rubygems,namespaced myfirst.thrift

Watch out, because you won't get any error message if you misspell...
