## Proposed changes Issue Number: close #xxx <!--Describe your changes.--> We found that when the unique-key table is upgraded from a version that does not support MOW (e.g. 1.1.5) to a version that supports MOW (e.g. 1.2.1), and then further upgraded to 2.0-beta, an issue occurs where MOR (Merge On Read) changes to MOW (Merge On Write). Therefore, this code is primarily aimed at fixing this problem. When a unique-key table does not have the property "ENABLE_UNIQUE_KEY_MERGE_ON_WRITE," it means that it was upgraded from a version that does not support the Merge On Write feature. Therefore, this table is using Merge On Read, and as a result, the value of "ENABLE_UNIQUE_KEY_MERGE_ON_WRITE" should be false, but in FE, our code mistakenly regarded it as true. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
