Finally I found a solution to my own question.
Google store has problem with id/name recognition in java entities
defines as Long:
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
To solve the this, an import_transform for the bulkloader config is
needed:
import_transform: transform.create_foreign_key('Kind', key_is_id=True)
Done.
