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.
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.
