RelNode inputs after being pushed into Druid

I'm wondering whether the input(s) of various RelNodes are important/are used after they are pushed into DruidQuery. What are the implications if they are not correct/have been altered?

RelNodes are immutable (or at any rate, you should treat them as such). If you change them after you have added them to DruidQuery bad things will happen.
