I was able to get distributed writes working smoothly for my use case. Tasks in a Ray cluster use `_dataframe_to_data_files` to write the data files to S3, then the resulting DataFile objects are aggregated by a central actor for a large delete + append transaction. Fortunately the Ray serialization (cloudpickle) works out of the box for DataFile objects so no additional work was required there. [MOR](https://github.com/apache/iceberg-python/issues/1078) would be helpful in the case where a lot of data needs to be deleted, ideally I could offload the large scale compaction/rewrites to AWS Athena or Glue since the Python support for that isn't quite there. -- This is an automated message from the Apache Git Service.
