AP4R Description

AP4R, Asynchronous Processing for Ruby, is the implementation of reliable asynchronous message processing. AP4R, Asynchronous Processing for Ruby, is the implementation of reliable asynchronous message processing. It provides message queuing, and also message dispatching.Using asynchronous processing, we can cut down turn-around-time of web applications by queuing, or can utilize more machine power by load-balancing. Here are some key features of "AP4R":· Business logics can be implemented as simple Web applications, or ruby code, whether it's called asynchronously or synchronously.· Asynchronous messaging is reliable by RDBMS persistence (now MySQL only) or file persistence, under the favor of reliable-msg.· Load balancing over multiple AP4R processes on single/multiple server(s) is supported.· Asynchronous logics are called via various protocols, such as XML-RPC, SOAP, HTTP POST, and more.About Ruby:Ruby is a dynamic, reflective, general purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. Ruby originated in Japan during the mid-1990s and was initially developed and designed by Yukihiro "Matz" Matsumoto.Ruby supports multiple programming paradigms (including functional, object oriented and imperative), and features a dynamic type system and automatic memory management; it is therefore similar in varying respects to Python, Perl, Lisp, Dylan, and CLU.In its current, official implementation, written in C, Ruby is a single-pass interpreted language. As there is currently no specification of the Ruby language, this implementation is considered the de facto reference. As of 2008, there are a number of alternative implementations of the Ruby language, including Rubinius, JRuby, YARV, and IronRuby, each of which takes a different approach, with JRuby providing just-in-time compilation functionality.The language was created by Yukihiro Matsumoto, who started working on Ruby on February 24, 1993, and released it to the public in 1995. "Ruby" was named as a gemstone because of a joke within Matsumoto's circle of friends alluding to the name of the Perl programming language.As of December 2007, the latest stable version of the reference implementation is 1.8.6. Apart from the reference, several other virtual machines are being developed for Ruby. These include JRuby, a port of Ruby to the Java platform, IronRuby, an implementation for the .NET Framework produced by Microsoft, and Rubinius, an interpreter modeled after self-hosting Smalltalk virtual machines.Requirements:· Ruby
