> ABFS: Support Photon (Apache Arrow) based ListBlobs on Blob endpoint with XML 
> fallback
> --------------------------------------------------------------------------------------
>
>                 Key: HADOOP-19941
>                 URL: https://issues.apache.org/jira/browse/HADOOP-19941
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: fs/azure
>            Reporter: Manish Bhatt
>            Assignee: Manish Bhatt
>            Priority: Major
>              Labels: pull-request-available
>
> Add config-gated support (fs.azure.photon.enabled, default off) for consuming 
> ListBlobs responses in the Apache Arrow (Photon) format on the ABFS Blob 
> endpoint. When enabled, ABFS advertises Arrow via an Accept header; the 
> response Content-Type selects an Arrow or the existing XML parser, both 
> producing identical FileStatus results, so downstream behaviour is unchanged. 
> Includes automatic, transparent fallback to XML, full parsing parity 
> (metadata, directory markers, implicit directories, copy properties, native 
> timestamp/length vectors), interrupt-safe Arrow parsing, and Photon telemetry 
> (request, response, fallback, parse-failure counts and listing latency). No 
> public API changes. Covered by unit and integration tests.
