------------------------------------

             Summary: Client should support re-attachable execution
                 Key: SPARK-51530
                 URL: https://issues.apache.org/jira/browse/SPARK-51530
             Project: Spark
          Issue Type: Sub-task
          Components: Connect
    Affects Versions: 4.0.0
            Reporter: Martin Grund


Right now, the client only supports the execution of blocking queries with no 
reattach. This makes it hard to use Spark Connect in cloud environments as 
cloud load balancers will typically hard-kill idle connections.

Similar to the Rust and Go client, it would be great if the client uses the 
reattache execution flow by default.
