Greenplum source

and target

objects represent metadata for Greenplum tables. You can define properties in the mapping to determine how the gpload utility reads

or writes data to

Greenplum. When you run a mapping, the Secure Agent invokes the gpload utility to read data from

or load data to

Greenplum.

In advanced mode, the Mapping Designer updates the mapping canvas to include transformations and functions that enable advanced functionality.
