I think what he is saying is that the csv files may not always have all the
columns, in which case they won’t parse, which is before stellar can do
anything.

A better way of doing this would be to use the fieldTransformation setting
and the REMOVE method to get rid of the extraneous fields. Docs are

That way you don’t need a separate preprocessing step.

No, there is no way to do this currently.
The parser parses the line into and array of strings that must match the
size of the columns.
The underlying opencsv parser does not support this either. You may have
to do some normalization work on your data if you need to account for this.

Is there any way to mark some columns as optional in column mapping in CSV
parser.
Thanks and Regards,
