Class MigrationNamespaceSerializerProxy

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<Serializable>

org.apache.flink.migration.MigrationNamespaceSerializerProxy

All Implemented Interfaces:

Serializable, TypeDeserializer<Serializable>

Deprecated.

Internal class for savepoint backwards compatibility. Don't use for other purposes.

@Deprecated
public class MigrationNamespaceSerializerProxy
extends TypeSerializer<Serializable>

The purpose of this class is the be filled in as a placeholder for the namespace serializer when migrating from Flink 1.1 savepoint (which did not include the namespace serializer) to Flink 1.2 (which always must include a (non-null) namespace serializer. This is then replaced as soon as the user is re-registering her state again for the first run under Flink 1.2 and provides again the real namespace serializer.
