Steve Loughran commented on HADOOP-17961:
-----------------------------------------
note: big assumption here, that the services stream the output, rather than
build up a document and then serve it. timeout behaviours on s3 with versioned
buckets and the v1 API hint that this holds there
> s3 and abfs incremental listing: use SAX parsers to stream results to list
> iterators

> Key: HADOOP-17961
> URL: https://issues.apache.org/jira/browse/HADOOP-17961
> 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
