> There might be nested AND cases:
> a = b AND (c = d AND (e = f)).
> Such cases should be flattened as a = b AND c = d AND e = f.
> This is useful because after done so, we can easily build keys for join
> inputs: each conjunction clause contributes a field of key (key is Row in SQL
> equi-join) for join inputs.
