- A Dimensional Model Moves Less Mass into Memory
- Which Move From Disk to Memory Would You Choose?
- Vworkers transfer their Fact Table into Memory in Parallel
- Modeling Rule 2 – Use Columnar
- Which Move From Disk to Memory Would You Choose?
- Let's Discuss Modeling and Joins at the Simplest Level
- Modeling Rule 3 – Distribute your Tables Based on Joins

- Fact and Dimension Tables can be Hashed by the same Key
- Joining Two Tables with the same PK/FK Primary Index
