MaxCompute 表的partition分区在表定义之后的如何进行增删？

你好我遇到过同样的问题，得到的答案是不可以。只能drop table重新建表，这是同学给我的解答，希望有帮助

分区表实际就是对应分布式文件系统上的的独立的文件夹，该文件是夹下是该分区所有数据文件。而分区可以理解为分类，通过分类把不同类型的数据放到不同的目录下
I don't think this is directly possible. would have to completely rearrange and split the files because adding the partition would impose a new directory structure.
What I suggest you do is simply create a new table with the desired schema and partition, and insert everything from the first into the second.

不支持新增/删除分区字段。
