Juliusz Sompolski updated SPARK-43754:
--------------------------------------
Affects Version/s: 4.0.0
> 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, 4.0.0
> Reporter: Juliusz Sompolski
> Priority: Major
>
> 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
