33 Optimizing Database Restructuring
Some changes to an Essbase block-storage database outline affect the data storage arrangement, forcing a restructuring of the database. Because changes that require restructuring the database can be time-consuming (unless you discard the data before restructuring), consider deciding on such changes based on how they affect performance.
The information in this chapter applies only to block storage databases and is not relevant to aggregate storage databases.
