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.
