Abstract

A first store and a second store can be configured to store a first partition of a table of a database and a second partition of the table of the database, respectively. A database management system can be configured to at least update at least a first portion of the first partition where the update includes an update to a first primary key column in the first partition and verify that the first primary key column is unique across the first partition and the second partition. A first row having a first primary key value of the first primary key column from the first partition can be deleted, when the first primary key value in the first partition conflicts with a second primary key value of a second primary key column in the second partition.
