    Description

      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:

      ,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。
