> During the work in SPARK-38204, I figured out the parameter is swapped which led to test failure on new test (I disabled the schema check for now in the PR of SPARK-38204).
> That allows nullable column to be stored into non-nullable column, which should be prohibited. This is less likely making runtime problem since state schema is conceptual one and row can be stored even not respecting the state schema.
> The worse problem is happening in opposite way, that disallows non-nullable column to be stored into nullable column, which should be allowed. Spark fails the query for this case.
> We should fix this to allow the case properly.
