> Large-scale listing of directory contents takes a lot longer time and also has the potential to run into OOM. I have > 1 million entries in the same level and it took lot longer time with {{RemoteIterator}} (didn't complete as it was stuck in RDB::seek).
> S3A batches it with 5K listing per fetch IIRC.  It would be good to have this feature in ozone as well.
