Lessons learned
New application: Retrieve all data for a TV
series (seasons, episodes, actors, and so on)
Perfect for a NoSQL database
– One simple retrieval returns all information
– Much simpler than relational database; no joins
Future use cases unknown
And then, a new feature request: Retrieve all data
for a given actor
Incompatible with original NoSQL document model
‘Actors’ cannot be retrieved separately
Simple feature to add with relational database
Just another SQL query on the same schema

feature convergence on essentials
1. Transactions
2. Standards : SQL, Indexes
3. Secure : Auth, Roles, Audit
4. HA : Data Centers
