An Amazon Redshift data object is a physical data object that uses Amazon Redshift as a source or target. An Amazon Redshift data object represents the data in an Amazon Redshift data source.
You can configure the data object read and write operation properties that determine how data can be read from Amazon sources and loaded to Amazon Redshift targets. You first create a connection to create an Amazon Redshift data object. Create a data object operation for the Amazon Redshift data object. Then, you can add the data object read or write operation to a mapping.

When you import an Amazon Redshift table in the Developer tool, you can add nullable columns in the table. However, you must not add the nullable columns as primary keys in the table.
