Hi @RussellSpitzer , does it mean that in the following case
```
MERGE INTO iceberg_hive_cat.iceberg_poc_db.iceberg_tab target
USING (SELECT * FROM source)
ON target.col1 = source.col1 AND target.purchase_date = source.purchase_date
```
where pruchase_date is the partition key of the target table, the pushdown
will happen as well?
Can I expect an almost same performance as for `INSERT INTO`, when the
source table doesn't share the same partitions (here `purchase_date`s) at all?
