             Summary: Add syntactic sugar for Iceberg Row Lineage data
                 Key: IMPALA-14825
                 URL: https://issues.apache.org/jira/browse/IMPALA-14825
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Zoltán Borók-Nagy


Currently Row Lineage fields can be queried by complex expressions:
 * row-id
 ** COALESCE(_file_row_id, ICEBERG__FIRST__ROW__ID + FILE__POSITION)
 * last-updated-sequence-number
 ** COALESCE(_file_last_updated_sequence_number, ICEBERG__DATA__SEQUENCE__NUMBER)

We could add ICEBERG__ROW__ID and ICEBERG__LAST__UPDATED__SEQUENCE__NUMBER virtual columns that would always get re-written during analysis.
