Public Interfaces

• New class org.apache.kafka.common.serialization.ListSerializer which implements the Serializer<List<T>>interface
• New class org.apache.kafka.common.serialization.ListDeserializer which implements Deserializer<List<T>> interface
• New subclass ListSerde<T> in org.apache.kafka.common.serialization.Serdes which creates new serde based on ListSerializer and ListDeserializer classes
• New method public static <T> Serde<List<T>> ListSerde() in org.apache.kafka.common.serialization.Serdes class (infers list implementation and inner serde from config file)
• New method public static <T> Serde<List<T>> ListSerde(Class listClass, Serde<T> innerSerde) in org.apache.kafka.common.serialization.Serdes class

Proposed Changes

This KIP proposes adding new ListSerializer and ListDeserializer classes as well as support for the new classes into the Serdes class. This will allow using List<T> Serde directly from Consumers, Producers and Streams.
