Pavel Pereslegin updated IGNITE-24564:
--------------------------------------
Description:
In order to migrate to the new serialization protocol.
1. Need to introduce annotation class
{code:java}
@Target(ElementType.TYPE)
@Retention(RUNTIME)
public @interface CatalogSerializer {
/**
* Returns serializer version.
*/
short version();
/**
* Returns the type of the object being serialized.
*/
MarshallableEntryType type();
/**
* The product version starting from which the serializer is used.
*/
String since();
}
{code}
2. Annotate all existing serializers with @CatalogSerializer(version=1,
since="3.0.0", type=<type>)
3. Move all existing serializers to separate package (this will required make
missing methods to access private fields of descriptors).
4. Implement serializer registry building.
{code:Java}
interface CatalogEntrySerializerProvider {
// New method is used to obtain serializer of specific version.
CatalogObjectSerializer<MarshallableEntry> get(int version, int typeId);
// Used to obtain the newest serializer version.
int latestSerializerVersion(int typeId);
}
{code}
During initialization registry must scan serializer folder and build registry
of available serializers.
