hubgeter opened a new pull request, #65610:
URL: https://github.com/apache/doris/pull/65610
_create_column_ids resolved every projected slot to a file column by name
through the schema-mapping StructNode. Synthesized/metadata slots such as the
TopN global row-id and the $row_id column are never serialized into the schema
tree, so they are not registered as struct children. Asking the node about them
made StructNode::children_column_exists() hit its
DCHECK(children.contains(name)) and abort (and throw std::out_of_range from
.at() in release builds), crashing Parquet/ORC reader init on a TopN projection
over an Iceberg table.
Restore matching by Iceberg field id (col_unique_id): synthesized slots
carry a sentinel col_unique_id that is not a real field id, so they miss the
field-id map and are skipped, exactly as before. Drop the now-unused
table_info_node parameter from both the Parquet and ORC overloads.
