I wanted to get a feel for how Apache Cassandra works, so I downloaded and installed (just copied) the files. I decided to run the single node test. Here's what I did on my Windows 7 laptop:

1) Download and unzip the latest Cassandra zip file to some folder - D:Dumpapache-cassandra-0.6.3
2) Open a command prompt at the main Cassandra directory and type - bincassandra.bat
3) That's it! You have a single node server that is running with the defaults. It creates and starts logging to some default location. In my case it was - D:varlibcassandra

Now, I wasn't too happy with the default Keyspace configuration - this is the "schema". So, I shut down the server, deleted the log directory and modified the configuration file in confstorage-conf.xml. I simplified the Keyspace to 2 simple sub-sets - a column family called Message and a super column family called Car.

The more I look at the Cassandra column family structure, the more it reminds me of XML.
