------------------------------------
Got it! Thx. I will explore implementing this by Hive primary key syntax.
> Iceberg: Add identifier-field-ids support in Hive
> -------------------------------------------------
>
> Key: HIVE-28015
> URL: https://issues.apache.org/jira/browse/HIVE-28015
> Project: Hive
> Issue Type: Improvement
> Components: Iceberg integration
> Affects Versions: 4.0.0
> Reporter: Denys Kuzmenko
> Assignee: Butao Zhang
> Priority: Major
>
> Some writer engines require primary keys on a table so that they can use them
> for writing equality deletes (only the PK cols are written to the eq-delete
> files).
> Hive currently doesn't reject setting PKs for Iceberg tables, however, it
> just ignores them. This succeeds:
> {code:java}
> create table ice_pk (i int, j int, primary key(i)) stored by iceberg;
> {code}
