Tzu-Li (Gordon) Tai updated FLINK-6191:
---------------------------------------
Description:
This sub-task follows after FLINK-6190.
For non-primitive type serializers internally created by Flink, we need to
allow them to be reconfigurable whenever we detect a change between the
previous and current serializer configuration.
Most notably, this is relevant for the {{KryoSerializer}} and
{{PojoSerializer}} which are affected by the configuration, as well as
composite types which can potentially have nested serializers (e.g.
{{GenericArraySerializer}}).
Since not all serializers require / reconfiguration, we propose to have a
extended abstract base class for these:
{code}
@Internal
public abstract class ReconfigurableTypeSerializer<T> extends TypeSerializer<T>
{
void abstract reconfigure(SerializersConfig serializersConfig);
}
{code}
This class is also used as a tag, to check if a serializer needs to be
reconfigured when serializer configuration change is detected.
