    Notice that we serialize Set to Catalyst array.

    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.
