    Notice that we serialize Set to Catalyst array. The set property is only kept when manipulating the domain objects. The serialization format doesn't keep the set property. When we have a Catalyst array which contains duplicated elements and convert it to Dataset[Set[T]] by using the encoder, the elements will be de-duplicated.
