[jira] [Created] (SPARK-53455) Add clone session API to Spark Connect

Venkata Sai Akhil Gudesa created SPARK-53455:
------------------------------------------------

             Summary: Add clone session API to Spark Connect
                 Key: SPARK-53455
                 URL: https://issues.apache.org/jira/browse/SPARK-53455
             Project: Spark
          Issue Type: Improvement
          Components: Connect
    Affects Versions: 4.1.0
            Reporter: Venkata Sai Akhil Gudesa


Spark Connect introduced the concept of resource isolation (via ArtifactManager which has seen been ported to classic Spark) and thus, jars/pyfiles/artifacts added to each session are isolated from other sessions.

A slight rough edge is that if a user wishes to fork the state of a session but maintain indepence, the only possible way is to create a new session and reupload/reinit all base jars/artifacts/pyfiles etc.

Support for cloning through the API helps address the rough edge while maintaining all the benefits of session resource isolation.
