  # In the v2 protocol, CREATE does not contain an empty row preceding statistics
  return unless response.length > 1

  # Any non-empty result set will have multiple rows (arrays)

  # First row is header describing the returned records, corresponding
  # precisely in order and naming to the RETURN clause of the query.
  header = response[0]

  # Second row is the actual data returned by the query
  # note handling for encountering an id for propertyKey that is out of
  # the cached set.
