   @qingfei1994 Sorry for the delayed response. Not only the `writer` will use it, but the `reader` also needs to merge. I think we can perform a check on `MergeFunctionFactory` before submitting the job, and throw an exception in advance if there is an exception. How about adding a `validateMergeFunctionFactory` method in `PrimaryKeyTableUtils`? `MergeFunctionFactory` is created using `PrimaryKeyTableUtils`.
