Operational Considerations
Checkpointing and Restarting
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.
When Teradata PT loads JSON, XML, or LOB data into a target table on Teradata Database from external data files, the SQL Inserter operator can take user-defined interval checkpoints during the load job.
