This document discusses various aspects of a media and feed service layer. It provides average call response times for different services, including Pulse at 4000ms, Capsule Feed at 2000ms, and Profile Feed at 2500ms. It also outlines the responsibilities of different service layer modules, including creating relationships and media records, adding content to feeds, and updating information in databases like MongoDB, Riak, Neo4j, and Cassandra.

Editor's Notes
- Have bobby fill out
- Explain what a social based social network is Focus on brands, and size
- Capsule are like folders for content
- Why This Approach What benefits do you gain How we wanted to make sure we where using the database tools correctly
- Identify issues with this approach - Creates take a long time - Service layer doing to much work - If errors any where in stack whole thing errors
- Why moving anything other than writes helps with speed and simplicity
- Add something about dispatchinator event/error handling
- Speed of dispatcher Analytics goes through millions of records per second
- Why this is faster No longer need to hydrate media object
- Capsule update diagram Explain why we need this
- Explain Justin Bieber affect, nMedia items for capsule
- Explain how worker works
- Explain step by step (slowly)
