If we decide to choose one, we need more test cases. This pr focus on random read of Array column, `offset version` is better than `length version` in this case. Other cases, such as sequence read, we also need to compare. Please add my wechat (doris_cambyzju). -- This is an automated message from the Apache Git Service.
