Cassandra is a highly scalable distributed database. It combines the
fully distributed design of Amazon’s Dynamo and the Column Oriented
functionality of Google’s Bigtable and has been deployed at some
extremely high-volume sites like Twitter and Digg. However its
terminology of Columns, SuperColumns and ColumnFamilies can be quite
confusing.

CassandraObject is a library which gives you a familiar
API when working with Cassandra. Built on ActiveModel you get all the
validations, callbacks and associations which your application relies
on, but with the scalability and performance of cassandra.

This talk will provide you with an overview of cassandra itself and cover the
differences between ActiveRecord and CassandraObject. It’ll also
provide some lessons learned from working with ActiveModel for people
who are interested in creating their own custom object mappers.

I walked into this session not knowing too much about Cassandra. In very short order, Michael gave a very clear/concise overview of what Cassandra and CassandraObject are. Thanks!

Perfect balance of high level education and low level examples by a great presenter. Thanks.
