> we also need to implement the custom Kryo Serializers for the network transfer btw writer and committer We can use Flink `DataFileTypeSerializer` to network too. +1 to store all the DataFile objects in a `ManifestFile`. But I think it is good to introduce `SimpleVersionedSerializer`s[1] for `DataFile` and `ManifestFile` too, we may need `FlinkDataFile` and `FlinkManifestFile`. The `SimpleVersionedSerializer` is a simpler design than `state-serializers-and-schema-evolution`, it is completely internal implementation in iceberg serializers.
