Cassandra in Action with Twitter's Ruby Client

有一个全新的项目，因为考虑到将来的数据扩展性能，所以考虑用Cassandra做数据存储，前端用Lighttpd + FastCGI + Rails。在使用Cassandra的时候，觉得有一些东西可能大家都需要，就写了一个简单的指南。因为内容比较长（16页），就弄了个PDF文件给大家下载。

Okay, let me get something straight. I’m not going to persuade you to use Cassandra. I just assume you have already chosen Cassandra as your storage solution. Maybe you know the basic things, the underneath mechanisms, about Cassandra or maybe not. Anyway, I assume you don’t care what makes Cassandra outstanding and you just want to use it. If that’s the case, this tutorial is going to help you, in these 3 aspects:
 
1) to set up the environment correctly,
2) to understand how to model you data in a Cassandra way,
3) to understand and use Twitter’s Cassandra Ruby client.
 
After reading this tutorial, you should have a working environment and can start your project with a good understanding of doing your job in a very Cassandra way. Here we go!
