> Spark supports a per-statement `WITH (key = value)` dynamic table options clause on all queries. When a single statement references the same table more than once with different options, only the first-resolved reference's options are honored; the other reference's options are silently dropped.
> Examples (each drops one side's options):
> {{INSERT INTO t WITH (`write.split-size` = 10) SELECT * FROM t}}
> {{MERGE INTO t WITH (`write.split-size` = 10)}}
> {{USING t WITH (`split-size` = 5) s}}
> {{ON t.id = s.id}}
> {{WHEN MATCHED THEN UPDATE SET ...}}
> {{UPDATE t WITH (`write.split-size` = 10) SET ...}}
> {{WHERE id IN (SELECT id FROM t WITH (`split-size` = 5))}}
