摘要：
A method and system for optimizing data redistribution in a database. In one embodiment, the method includes moving, during a first scan, outgoing records from a sending partition to one or more receiving partitions, where free space is created in the sending partition due to the outgoing records leaving the sending partition. The method also includes filling, during the first scan, some of the free space with remaining records that do not leave the sending partition.
