> Full description of the new protocol
> https://github.com/ggprivate/gridgain-9/pull/1790/files?short_path=b620061#diff-b6200614bc71e194a446cad5d275138fedf1e1f4ffde59b5be17e2fc8c93fc54
> 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 activeSerializerVersion(int typeId);
> }
> {code}
> During initialization registry must scan serializer folder and build registry
> of available serializers.
