> attempts
> -----------------------------------------------------------------------------------
>
> Key: SPARK-53329
> URL: https://issues.apache.org/jira/browse/SPARK-53329
> Project: Spark
> Issue Type: Improvement
> Components: Connect
> Affects Versions: 4.1.0, 4.0.1
> Reporter: Venkata Sai Akhil Gudesa
> Assignee: Venkata Sai Akhil Gudesa
> Priority: Major
> Labels: pull-request-available
>
> When a user sends multiple artifacts with the `addArtifacts` API, we process
> each artifact one at a time on the server-side.
> If the server detects the user attempting to modify an artifact (by
> overwriting an existing artifact of the same path with a different byte
> sequence), an exception is immediately thrown and artifact addition process
> is terminated.
>
> This can be a bit wasteful as the server discards all other artifacts sent
> over the wire regardless of their own status. Thus, an improvement can be
> made to process all artifacts, catch any exceptions and rethrow them at the
> end.
> This can potentially save bandwidth by avoiding multiple transfers. Further,
> retry logic is unimpacted as we currently do NOT throw an error when
> attempting to "overwrite" an existing file with the same bytes.
