This task tracks work involved with completing the first release of the "Metrics Platform," which is a software suite consisting of:

• Event Platform Client Libraries
• Event Stream Configuration
• Event Schema

These components exist today but are not interacting according to a unified design, and this is what the first release will bring.

The system will operate on a concept called "Analytics-By-Contract". In this system, roles are divided into data producers and data consumers.

• Data producers: engineers who add instrumentation to product code. Each instrument sends an event, which consists of a name and some data.
• Data consumers: data scientists who define a dataset using a stream configuration, deploys the stream, and begins querying data in the database.

The "contract" is a piece of configuration called a "stream configuration". The job of the Event Platform Client Library is to fulfill the contract.
