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.

If a checkpoint interval is specified on the tbuild command line, the checkpoints incurred between the start of data loading and the end of data loading are ignored by the Export operator.
