Permanent metadata entities are the following:
- Dimensions
- Hierarchies
- Levels
- Level properties
- Named sets
- Members of the Measure dimension
- Hierarchy default members
When an ODBO client requests a cube, all of the cube’s permanent entities are pre-loaded from the Teradata BI Model Repository. These entities are cached for the duration of the ODBO session. There is no limit placed on the maximum number of entities in this category. The assumption is that the number of permanent entities is always going to be low.
