Row equality does not work for java data structures (e.g. List).

In current implementation, Row's equals uses Objects.deepEquals, which only deeply compare array. For example, List will not be deeply compared because this function will just call List.equals.

Map might not have the correct equals as well.

If there is no other option, we might need to have a customized deep equal to handle all cases we have.
