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.
