Management of intelligent data assignments for database systems with multiple processing units

摘要

Data of a database (e.g., database tables) can be reassigned from a first map to a second map in a database system that uses maps to assign data for processing to multiple processing units of a database system in accordance with one or more distributions schemes. Data portions can be selected in groups and moved in the selected groups in an efficient manner. The selection and/or movement of the data portions can be automated without requiring input for users of database systems.
