After the data is loaded to the nodes of the Vertica database, Vertica distributes the load across the data nodes using an optimization strategy known as projections. Vertica recommends that you enable automatic projections initially. Later, you may choose to use the Vertica Database Designer to manually create projections that optimize your database based on the characteristics of the data and, optionally, the queries you use.
For information on Vertica projections, see the “Automatic projection creation” topic in the Configuring the Database section of the Vertica Enterprise Administrator’s Guide.
