|Append new entities only. Existing entities or their original values will not be modified. No client-side changes are lost in this merge. This is the default behavior.|
|Objects are always loaded from persisted storage. Any property changes made to objects in the object context are overwritten by the data source values.|
|All current values on the client are overwritten with current values from the data service regardless of whether they have been changed on the client.|
|Current values that have been changed on the client are not modified, but any unchanged values are updated with current values from the data service. No client-side changes are lost in this merge.|
