在 TypeORM 中创建新记录时，保存和插入有什么区别

Question

当想要创建新记录时.save()和.insert()in之间有什么区别？Repository

代码中，注释为.insert()：

// From https://github.com/typeorm/typeorm/blob/b6c828cc6c9786c155165d97e1f21af7cf423075/src/repository/Repository.ts#L224-L232


    /**
     * Inserts a given entity into the database.
     * Unlike save method executes a primitive operation without cascades, relations and other operations included.
     * Executes fast and efficient INSERT query.
     * Does not check if entity exist in the database, so query will fail if duplicate entity is being inserted.
     */
    insert(entity: QueryDeepPartialEntity<Entity>|(QueryDeepPartialEntity<Entity>[])): Promise<InsertResult> {
        return this.manager.insert(this.metadata.target as any, entity);
    }

代码中，注释为.save()：

// From https://github.com/typeorm/typeorm/blob/b6c828cc6c9786c155165d97e1f21af7cf423075/src/repository/Repository.ts#L140-L151

    /**
     * Saves a given entity in the database.
     * If entity does not exist in the database then inserts, otherwise updates.
     */
    save<T extends DeepPartial<Entity>>(entity: T, options?: SaveOptions): Promise<T & Entity>;

    /**
     * Saves one or many given entities.
     */
    save<T extends DeepPartial<Entity>>(entityOrEntities: T|T[], options?: SaveOptions): Promise<T|T[]> {
        return this.manager.save<Entity, T>(this.metadata.target as any, entityOrEntities as any, options);
    }

我不明白什么是：

与 save 方法不同，它执行原始操作，不包含级联、关系和其他操作。
