Can not change UNIQUE KEY to Merge-On-Write mode

[LCehoennardo]

将一个unique模型的表从Merge-On-Read转为Merge-On-Write报错：

alter table dor_unique_table_rt set ("enable_unique_key_merge_on_write"="true")

报错：

Execution failed: Error Failed to execute sql: java.sql.SQLException: (conn=848962) errCode = 2, detailMessage = Can not change UNIQUE KEY to Merge-On-Write mode

这个参数不支持更改吗？

不支持mor和mow的互换吧

不支持mor表转换成mow表，只能重新建表。
