-Quick note on using MySQL Workbench to design data warehouses
Transitioning to the physical design:
-How to decide on the right storage engine(s)
-When to/not to use row and column-oriented storage engines
-How to decide on a partitioning strategy
-Optimizing for fast data loads
-The love-hate relationship with indexes
-Hardware architectures: SMP, MPP, or both?
-Use case benchmarks for the above designs
Monitoring and tuning the design:
-Monitoring checklist (database, OS, and storage)
-SQL diagnostic troubleshooting best practices
-When to quit and start over
