docs: If simulate is set to true, this will simply return.
  If version is pointing to an empty location, drop the partition and close the jdbc connection.
  If version is pointing to the same location as of the dataset, then drop the partition and close the jdbc connection.
  If version is pointing to the non deletable version locations, then drop the partition and close the jdbc connection.
  Otherwise delete the data underneath, drop the partition and close the jdbc connection.
