I would suggest to implement 1 first as it's easier, what do you think? Is position delete must be sorted or it just be optional? From the iceberg spec, it looks like it must be sorted. https://iceberg.apache.org/spec/#position-delete-files:~:text=The%20rows%20in%20the%20delete%20file%20must%20be%20sorted%20by%20file_path%20then%20pos%20to%20optimize%20filtering%20rows%20while%20scanning. -- This is an automated message from the Apache Git Service.
