> {{Utils.getIteratorSize}} is slightly slower than {{Iterator.size}} when
> using Scala 2.13, but it seems that we can't call {{Iterator.size}} directly,
> because {{Utils.getIteratorSize}} method returns {{Long}} type data, using
> {{Iterator.size}} directly can't ensure that overflow will not occur.
