The Export operator takes a checkpoint only when all data is sent to the data stream. If a restart occurs, the operator either must send all of the data or none of the data depending on whether the checkpoint has taken place.
- If all the data is sent, then the operator displays the following message and does not resend any of the data:
Restart indicates that this export job completed.
- If all the data is not sent, the operator terminates. Restart the job from the beginning.
- If none of the data is sent, the operator sends the data.
The Export operator does not support a user-defined restart log table.
