Guaranteed Processing
Ensures that the mapping processes messages that the sources publish 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.
By default, the Guaranteed Processing property is selected.

You can select one of the following options:
  • CUSTOM. Read messages from a specific time.
  • EARLIEST. Read the earliest messages available on the event hub.
  • LATEST. Read the latest messages from an event hub.
