             Summary: Spark Connect Session & Query lifecycle
                 Key: SPARK-43754
                 URL: https://issues.apache.org/jira/browse/SPARK-43754
             Project: Spark
          Issue Type: Epic
          Components: Connect
    Affects Versions: 3.5.0
            Reporter: Juliusz Sompolski


Currently, queries in Spark Connect are executed within the RPC handler.

We want to detach the RPC interface from actual sessions and execution, so that 
we can make the interface more flexible
 * maintain long running sessions, independent of unbroken GRPC channel
 * be able to cancel queries
 * have different interfaces to query results than push from server
