If somebody would have asked me few days back this question , I would not have known the answer. But I always wanted to find about the technology and tricks used at high performance sites like  twitter , facebook and ebay.

During discussions with one of the colleagues, I came to know that core of  twitter has been written in Scala. And that set me going . Twitter had really high load going to 5000 tweets per minutes at times.

I really wanted to find out more about Scala and learn about it.

What is Scala ?

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.

Many top-notch programmers and industry leaders have already been captivated by Scala. James Strachan even says that scala is the long term replacement of java and javac.
