I think I understand. There's one more point of confusion: we should only compare each column of the outermost RelDataType (Struct). However, in practice, if one of the columns is itself a Struct, we shouldn't allow its name to be changed (though I believe such changes would hardly ever occur in any optimization rule). So, should we only allow the field names at the first level to differ? -- This is an automated message from the Apache Git Service.
