Checkpoints are entries posted to a restart log table at regular intervals during the Teradata FastLoad data transfer operation. If processing stops while a Teradata FastLoad job is running, the job can be restarted at the most recent checkpoint.

If, for example, 1,000,000 records are being loaded into a table and they have specified checkpoints every 50,000 records, Teradata FastLoad pauses and posts an entry to the restart log table whenever multiples of 50,000 records have been successfully sent to the database. If the job stops after record 60,000 has been loaded, the job can be restarted at the record immediately following the last checkpoint, record 50,001.

Enable the checkpoint function by specifying a checkpoint value in the BEGIN LOADING command.
