    var title: String
) {
    @MongoId(FieldType.OBJECT_ID)
    var id: String? = null

    @CreatedDate
    var createdAt: LocalDateTime? = null

    @LastModifiedDate
    var lastModifiedAt: LocalDateTime? = null

        mongoTemplate.upsert(
            Query(Criteria.where("title").`is`("Hello")),
            Update().set("title", "Hi"),
