> Iceberg: Compaction: Allow only partition columns in the WHERE clause

> Key: HIVE-28537
> URL: https://issues.apache.org/jira/browse/HIVE-28537
> Project: Hive
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Components: Hive, Iceberg integration
> Reporter: Dmitriy Fingerman
> Assignee: Zoltán Rátkai

> Currently Hive Iceberg compaction supports any columns in the WHERE clause
> predicate. However, compaction happens only on partition level. Performance
> can be improved if the columns in WHERE clause predicate will be limited to
> partition columns.
> For example, Athena project supports only partition columns in the WHERE
> clause:
> [https://docs.aws.amazon.com/athena/latest/ug/optimize-statement.html]
> {code:java}
> Only partition columns are allowed in the WHERE clause predicate. Specifying
> a non-partition column will cause the query to fail.{code}
