Class ScalaNoneSerializer

com.esotericsoftware.kryo.Serializer<scala.None$>
com.here.platform.data.client.flink.serializers.ScalaNoneSerializer
public class ScalaNoneSerializer extends com.esotericsoftware.kryo.Serializer<scala.None$>
A dedicated serializer for the Scala None singleton.

In Apache Flink applications that utilize Scala libraries, particularly those involving the Scala Option type and its singleton instance None, serialization issues may arise from Kryo's deserialization of Scala objects. By introducing a custom serializer specifically for the None object, such deserialization issues can be effectively solved.
