> 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
