So we need something that is produced by `FileFormat::make_thing(FileScanConfig)` that can then create a FileOpener per partition, right? Partition is closer to Runtime Config (passed from execution plan's exec) so it should be ok to have only one FileFormat for all partitions. The partition number is used to get a set of file segments from FilsScanConfig and to mark metrics. -- This is an automated message from the Apache Git Service.
