One follow-up question I had is doesn't using the filesystem commitment protocol (atomic rename) require file listing? ```suggestion Iceberg has its own FileIO abstraction instead of depending on an external library (e.g. fsspec) because Iceberg doesn't require directories and other features of a file system. It only cares that it can read a file as a stream with seek, or write a file and get the byte position from time to time. We therefore define our own abstractions that can wrap other file-like implementations. ``` -- This is an automated message from the Apache Git Service.
