Speaker: Theo Hultberg, Chief Architect at Burt Video: http://www.youtube.com/watch?v=9vgKWPCztXw&list=PLqcm6qE9lgKLoYaakl3YwIWP4hmGsHm5e&index=13 I'm not a database driver expert, I'm just a Ruby developer who really likes Cassandra, but I've written a CQL driver. It wasn't hard, and it feels really good to now have an understanding of how my applications talk to Cassandra. To know what happens when I connect, prepare a statement, or how my data is encoded on its way to the database. When my CQL collections got big and I got weird results back, I could use my knowledge to quickly debug the issue. I'd like to give you an overview of the new native protocol from the driver perspective, maybe it can help you understand Cassandra the way it has helped me.
