If the delte filter matches entire partitions of the table, Iceberg will
perform a metadata-only delete. If the filter matches individual rows of a
table, then Iceberg will rewrite only the affected data files.
+### `UPDATE`
+
+Spark 3 added support for `UPDATE` queries to remove data from tables.
Review comment:
I've fixed it. I'll think about the complex updates for `MERGE INTO`
and add in another patch.
