plusplusjiajia opened a new pull request, #8570:
URL: https://github.com/apache/paimon/pull/8570
### Purpose
A cross-column mask (transform reads columns other than its target, e.g.
`display := concat_ws('-', first, last)`) threw at read time when the query
projected the masked target but not the mask's input columns:
`Column masking refers to field 'first' which is not present in output row
type`.
Row-filter operands are already added to the read projection and projected
back
out (#8447); this does the same for column-mask inputs in
`AbstractDataTableRead.authedReader`. Masks whose target isn't projected
are
skipped, so their inputs aren't collected.
