A method includes maintaining (302), by a publisher system (202), a data table (208) associated with a primary key PK-i. The method includes adding (306), by the publisher system (202), a unique value PK-g associated with every record of the data table (208). The method includes defining (308), by the publisher system (202), a primary key PK based on PK-i and PK-g. The method includes publishing (312) records from the data table (208), including the primary key PK, by the publisher system (202), to at least one subscriber system.
