* Talking about analytics reporting and tagging with Gavin

** Analytics view
Long-term goal (since 2014) is to move analytics to be pre-materialized using
stream processing.

The analytics view is intended to be the place a system goes to to retreive the
view of analytics it needs (e.g. hundreds of endpoints for specific use cases).

As a first step, we can set up a service hosting endpoints for our reporting
needs, and gradually evolve that into an analytics reporting service with
performant materialized views backing it.
** Tagging
- Campaigns processes one action per subscriber at a time, locking it.
- Tagging queues have priorities.
  - Have tagging operations with multiple tags emit events for each tag in the
    operation at different priorities, thus spreading out actions applied to a
    particular subscriber and reducing contention.
  - Have bulk tagging jobs apply at a different priority?
