[jira] [Created] (SPARK-42543) Specify protocol for UDF artifact transfer in JVM/Scala client

Venkata Sai Akhil Gudesa created SPARK-42543:
------------------------------------------------

             Summary: Specify protocol for UDF artifact transfer in JVM/Scala client 
                 Key: SPARK-42543
                 URL: https://issues.apache.org/jira/browse/SPARK-42543
             Project: Spark
          Issue Type: Improvement
          Components: Connect
    Affects Versions: 3.4.0
            Reporter: Venkata Sai Akhil Gudesa


An "artifact" is any file that may be used during the execution of a UDF.

In the decoupled client-server architecture of Spark Connect, a remote client may use a local JAR or a new class in their UDF that may not be present on the server. To handle these cases of missing "artifacts", a protocol for artifact transfer is needed to move the required artifacts from the client side over to the server side.
