    For Join operator, it is indeed complicated as you see. Due to different join type, the
output nullability is inferred in different way. However, the output of Join operator is also
inferred according to its join type.
    
    Btw, I think only Filter and Join will change output nullability with their condition.
Any other operator do that?
