  • Currently Spark Factorial supports factorials till 20 returning bigints.
  • Added similar support so that functions can be offloaded to Velox preventing fallbacks from Gluten side.
  • Using a lookup array since Spark just supports factorial till 20, and calculation would be expensive otherwise.
