Design Tables with Sample Data

You must specify one or more design tables for Database Designer to deploy a design. If your schema is empty, it does not appear as a design table option.

When you specify design tables, consider the following:

• To create the most efficient projections for your database, load a moderate amount of representative data into tables before running Database Designer. Database Designer considers the data in this table when creating the design.
• If your design tables have a large amount if data, the Database Designer run takes a long time; if your tables have too little data, the design is not optimized. Vertica recommends that 10 GB of sample data is sufficient for creating an optimal design.
• If you submit a design table with no data, Database Designer ignores it.
• If one of your design tables has been dropped, you will not be able to build or deploy your design.
