It cannot be used as a Key column. Now STRUCT can only used in Duplicate Model

The names and number of Fields in a Struct is fixed and always Nullable, and a
Field typically consists of the following parts.

并没有被删除，这是因为在底层的依赖关系上，会先判断key相同的情况，对外展示sequence列的值大的行数据，然后在看该行的`__DORIS_DELETE_SIGN__`值是否为1，如果为1则不会对外展示，如果为0，则仍会读出来。

CDC场景中），使用seq列可以有效的保证当数据乱序到达时的一致性，避免后到达的一个旧版本的删除操作，误删掉了先到达的新版本的数据。**
