The SQL Inserter operator takes two basic checkpoints, a start-of-data checkpoint and an end-of-data checkpoint, during a load operation so that the SQL Inserter operator can restart automatically when the load operation is interrupted by a Teradata Database restart, should one occur.

After an error, the Inserter operator does not have the capability to restart the load job where it left off. Using the interval checkpoint is not recommended for most load jobs using the Inserter operator; however, if a target table is empty and millions of data rows with many JSON, XML, or LOB columns are loaded, the interval checkpoint option could be used to avoid a potential of dead-lock errors during the load job.
