Overwrite and Discard Methods

The overwrite and discard methods ignore the values from either the originating or destination site and therefore can never guarantee convergence with more than one master site. These methods are designed to be used by a single master site and multiple materialized view sites, or with some form of a user-defined notification facility.

The overwrite method replaces the current value at the destination site with the new value from the originating site. The discard method ignores the new value from the originating site.
