> 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:

> {code:java}
> Only partition columns are allowed in the WHERE clause predicate. Specifying a non-partition column will cause the query to fail.{code}
