### Search before asking - [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Motivation Currently `MergeEngine` is defined by paimon. Column-level merge functions can be customized through `FieldAggregator`, but users cannot customize row-level merge functions. This function mainly supports users to define their row-level merge functions. ### Solution _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
