【 使用环境 】生产环境 or 测试环境
【 OB or 其他组件 】ob及obdumper
【 使用版本 】ob4.1社区版 obdumper4.2.1
【问题描述】清晰明确描述问题
我在一个3节点集群中存储了一个数据集，大概200w+条数据，在一列上使用key分区：
ALTER TABLE power PARTITION BY key(Global_active_power) PARTITIONS 3;
我打算导出每个分区中的数据，尝试了obdumper的命令导出3个csv文件，但似乎存在问题。我该如何准确导出每个分区中的数据？
【复现路径】问题出现前后相关操作
【问题现象及影响】
导出数据后，确实是3个csv文件，但这每一个文件都有200w+的数据，但我期望的结果应该是这3个文件加一起才是200w+条数据。
下面是obdumper调用的日志：
