[ASTERIXDB-1130][STO]: JSON serialization for persisted objects
- user model changes: no
- storage format changes:
This change replaces the use of Java serialization for persisted objects
such as dataset/index metadata, checkpoints, ect...
This will break backward compatibly with any existing AsterixDB instance.
However, the change is needed to enable future backward compatibility support
for persisted objects.
- interface changes:
IJsonSerializable: contains API to serialize a class as a JsonNode.
IPersistedResourceRegistry: contains a mapping between an IJsonSerializable
class and a unique type id. An IPersistedResourceRegistry is responsible
for generating the class identifier in the JSON output.
The class identifier will always contain the following attributes:
@type: a unique type id that identifies the object type.
@version: the version of the serialized class.
@class: the serialized class full name.
Any registered class with PersistedResourceRegistry must provide
a static fromJson(IPersistedResourceRegistry, JsonNode) method for
deserialization. This is ensured during the class registration process.
