>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/azure, fs/s3
>    Affects Versions: 3.3.2
>            Reporter: Steve Loughran
>            Priority: Minor

> With code gradually adopting listStatusIncremental(), asking for a smaller initial batch could permit faster ramp of result processing.
> probably most significant on an s3 versioned bucket, as there the need to skip tombstones can result in significantly slower listings -but could benefit ABFS too
