------------------------------------------
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.
