TypeSerializerSnapshotWhen a checkpoint/savepoint is restored, this method checks whether the serialization format of the data in the checkpoint/savepoint is compatible for the format of the serializer used by the program that restores the checkpoint/savepoint. The outcome can be that the serialization format is compatible, that the program's serializer needs to reconfigure itself (meaning to incorporate some information from the TypeSerializerSnapshot to be compatible), that the format is outright incompatible, or that a migration needed. In the latter case, the TypeSerializerSnapshot produces a serializer to deserialize the data, and the restoring program's serializer re-serializes the data, thus converting the format during the restore operation.

as compatible. This method can be used as a hook and may be overridden to identify more compatible versions.
