Cassandra at Bazaarvoice

Bazaarvoice will be describing an internal datastore built on Apache Cassandra.

Introducing Bazaarvoice datastore (EmoDB)

EmoDB is a RESTful HTTP server used by Bazaarvoice for storing JSON objects and for watching for changes to those events. It also supports a blob store, a queueing service, and a data bus to track events.

It is designed to span multiple data centers, using eventual consistency (AP) and multi-master conflict resolution. It relies on Apache Cassandra for persistence and cross-data center replication.

About Bazaarvoice

Bazaarvoice is based on a simple truth - when people talk to each other, people buy stuff they are happy about because they trust the opinions of others. We see a day when all voices are connected and, together, help the marketplace function better. We’ve built a network that connects businesses together to amplify the authentic voices of people wherever they shop – online, in-store and mobile. Our mission, just like our name, is to be the "voice of the marketplace", one authentic conversation at a time. 

Each month, more than 450 million people view and share opinions, questions and experiences on more than 20 million products in the Bazaarvoice network. Our technology platform channels these voices into places that help consumers make purchasing decisions. Our engineers have the opportunities to work on many areas of computer science, including distributed computing, natural language processing, big data analytics, larget-scale system design, and user interface design just to name a few. We use the latest and greatest technologies in Cloud, NoSQL, advanced client side JavaScript etc to solve problems at a scale that few companies can offer.

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
