> 0.13.0 预发版2。
> 问题描述：
> 在执行跨空间合并时，停止iotdb，备份data，启动iotdb，执行count(*)，查询结果多数据。
> 问题2（猜测同IOTDB-2445）：
> Msg: 500: [INTERNAL_SERVER_ERROR(500)] Exception occurred: "select count(*) from root.test.g_2.d_2". executeStatement failed. java.io.IOException: overlapped data should be consumed first
> 复现流程：
> 1.关合并，bm生成测试数据，对齐序列，有乱序。
> 2. 开合并，执行合并，约6小时，停止iotdb，停止时的合并情况：
>  !image-2022-01-24-19-08-57-510.png! 
> ，备份data
> 3. 启动iotdb，执行100条查询：
> test.g_1.d_1设备查询多数据，所有序列的实际点数为12亿点。
