Thanks Steven - I will take a look.

Since your just starting out and it seems like you want to get past the admin hurdles and start coding, may I suggest you use to get your local test environment setup.

Setting up a production Cassandra cluster takes a fair amount of planning (before) and tuning (during/after) in my experience.  Both need to be done once you decide Cassandra is "right" for your data....ccm is nice in that you don't need to invest a lot in Cassandra to figure that out :-)

Hope this helps,

A quick question for you - I am completely new to noSQL databases and the architecture of Cassandra. So, I'm still way down the learning curve.

I downloaded and installed the OpsCenter last night, but I first need to configure it. I want to install 2 nodes on my laptop and then start building some code around it to move my DB from mySQL. I've had a look at the DataStax website for some info on the very basics - setting up nodes, configuration etc, but couldn't see anything. Is there anything there that you can point me at? Or alternatively, any other sites that provide a good overview with examples?

I see that Jonathan Ellis is in London Wednesday at the Cassandra group's talk so will try to drop by and say hello.

However, the crux is figuring out an easy way to import the data into Cassandra. Does anyone have any thoughts they can share?

If you don't have a very large dataset and you're not pressed for time, just iterating over your existing data with a normal mysql client and inserting into Cassandra with a normal Cassandra client is the easiest option.  Using multiple threads or processes can make this pretty quick.

For larger datasets, loading through a map/reduce job is typical.
In addition, are there any GUI tools like phpmyAdmin for Cassandra?

There's DataStax OpsCenter, which has a free Community Edition:
