> 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.
