Overview

The event model

Event documents are key-value pairs, represented in JSON. A document consists of a primary key called the topic (_id in mongodb). It belongs to a collection named "#organization_name.##topic.events"

Note: mongodb is passed in beacuse Goliath makes Thread lookups will not work while Goliath is in a streaming context.
