Labels: pull-request-available (was: )
> Support custom write metrics for shuffle storage plugins
> --------------------------------------------------------
>
> Key: SPARK-58206
> URL: https://issues.apache.org/jira/browse/SPARK-58206
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL
> Affects Versions: 4.3.0
> Reporter: Karuppayya
> Priority: Major
> Labels: pull-request-available
>
> Spark supports pluggable shuffle storage (ShuffleDataIO), so shuffle data can
> be written to substrates like a remote/external shuffle service, a
> distributed filesystem (HDFS), or the default local disk.
> However, plugins have no way to expose substrate-specific write metrics to
> users — e.g. bytes pushed to a remote shuffle service, or spill-file counts
> and fsync counts for local disk — so these remain invisible in the SQL UI.
> (Somewhat similar to the custom-metrics support that DSV2 sources already
> have.)
