csvNoSupValue property
This setting only applies if your Amazon S3 output files during a change
data capture (CDC) load are written in .csv format. If
UseCsvNoSupValue is set to true, specify a string value
that you want AWS DMS to use for all columns not included in the
supplemental log. If you do not specify a string value, AWS DMS uses the
null value for these columns regardless of the UseCsvNoSupValue
setting.
Implementation
final String? csvNoSupValue;
