   > @xccui I thought we can't make `DataStatisticsOrRecord` a true Pojo, because the `RowData` is not a POJO. we will provide `TypeSerializer` implementations for `DataStatistics` and `DataStatisticsOrRecord `
   
   Ah, yes, it's not that trivial. For `RowData`, `org.apache.flink.table.runtime.typeutils.InternalTypeInfo` can help, but overall, customized `TypeSerializers` would be nice to have 👍
