29. SQL Federation : Best Practices
 Federations
 Normalize your data model all the way
 Apply Scale-First design principles
 Select Table Groups that need Scale-out
 Federation Keys and Atomic Units
 Target latency and scale sensitive queries
 Ensure transaction boundaries
 Distribute the app workload equally across members
 Fit in the scale-up limit
 Unique Key Generation
 Identity
 Uniqueidentifier
