Want to go deep on a popular NoSQL database? Cassandra is a scalable, highly available, column-oriented data store in use at Netflix, Twitter, Reddit, Rackspace, and other web-scale operations. It offers a compelling combination of a rich data model, a robust deployment track record, and a sound architecture, making it a good choice of NoSQL databases to study first. In this session, we'll talk about Cassandra's data model, look at its query idioms, talk about how to deploy it, and look at use cases in which it is an appropriate data storage solution. We'll study its origins in the Amazon Dynamo project and Google's BigTable, and learn how its architecture helps us achieve the gold standard of scalability: horizontal scalability on commodity hardware. You'll leave prepared to begin experimenting with Cassandra immediately and planning its adoption in your next project.

Continuous Delivery

Continuous delivery is the current buzz phrase, but let’s take a few minutes together to demystify it.

  1. Does it work?
  2. How would you go about getting towards that mode of operation?
  3. Why would you want to have continuous delivery?
  4. What tools facilitate this?

You’ll leave a transformed developer. The idea of releases being non-stressful and able to be merged in on Friday at 4pm is attractive to the majority of us who have suffered at the hands of the “awful rollback” and the “long weekend.” These travails are partially the result of being on the opposite end of the spectrum from continuous delivery. Come with an open mind to branching strategies, feature toggles, and Readme driven development and let’s see how a little automation and agile thinking can glue them all together.
