Qu v2 notes

Qu v2 should be modular, and allow you to create your own Qu instance easily.

It should be made of the following components:

• qu-core, the heart of the Qu application
• lein-qu, a Leiningen template for building a Qu instance
• qu-mongo, the interface to MongoDB
• qu-postgres, a data interface to Postgres
• qu-*, other interfaces

While we eventually want a larger plugin architecture, abstracting and plugging in the data interfaces is enough for now.

qu-core will define several protocols:

• Query (currently exists)
• QueryResult/DataResult (haven't decided on name; currently exists as DataResult)
• DataSource (does not currently exist)

Use Stuart Sierra's component framework for each moving part:

• web server
• loader
• query cache

Use tools.namespace for managing plugins.
