Abstract
A database may be virtually partitioned into virtual partitions. The virtual partitions are mapped to physical databases of a database. Data records added to the database are each assigned to a virtual partition and stored in the physical database mapped to the assigned virtual partition. The identifier generated for a data record includes an identifier of the assigned virtual partition. When additional databases are created, virtual partitions are remapped to the larger space of physical databases.
