Teradata MultiLoad supports the use of checkpoints. Checkpoints are entries posted to a restart log table at regular intervals during the Teradata MultiLoad data transfer operation. If processing stops while a Teradata MultiLoad job is running, restart the job at the most recent checkpoint.
For example, assume 1,000,000 records are loading in a table and have specified checkpoints every 50,000 records. Then Teradata MultiLoad pauses and posts an entry to the restart log table whenever multiples of 50,000 records are successfully sent to Teradata Database.
If the job stops after record 60,000 has been loaded, restart the job at the record immediately following the last checkpoint—record 50,001.
Enable the checkpoint function by specifying a checkpoint value in the BEGIN MLOAD command. For more information, see “BEGIN MLOAD and BEGIN DELETE MLOAD” on page 104.
