A Data Mover job consists of the following:
- A user-provided definition of database objects that Data Mover copies from the source to the target, such as a copy of a table from the PROD1 Teradata Database system to the DEV1 Teradata Database system.
- A programmatically-generated plan of sequential and parallel tasks to optimize job execution, such as distributing job execution into tasks across several servers.
Data Mover jobs that are created with the command-line move command act the same as running the create command followed by the start command. The jobs continue to exist after execution, including job definition and history, whether successful or not. You can delete these jobs if they are no longer needed.
Only one instance of a specific job can run at one time.
