rows containing its fields/elements. Its result schema is `struct<pos int, key
string, value variant>`. `pos` is the position of the field/element in its
parent object/array, and `value` is the field/element value. `key` is the field
name when exploding a variant object, or is NULL when exploding a variant
array. It ignores any input that is not a variant array/object, including SQL
NULL, variant null, and any other variant values.",
