Property
Description
Operation Type
Specifies the type of data object operation.
This is a read-only property.
Guaranteed Processing
Guaranteed processing ensures that the mapping processes messages published by the sources and delivers them to the targets at least once. In the event of a failure, there could be potential duplicates but the messages are processed successfully. If the external source or the target is not available, the mapping execution stops to avoid any data loss.
Select this option to avoid data loss.
