milenkovicm opened a new issue, #1098:
URL: https://github.com/apache/datafusion-ballista/issues/1098

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   On the road to library transition I would like to expose more configuration 
(DataFusion specific) which user can tune. This would enable us to remove hard 
coded object stores, codecs, configuration extension, functions ...
   
   **Describe the solution you'd like**
   
   I would like to expose additional method in `executor/src/standalone.rs`:
   
   ```rust
   pub async fn new_standalone_executor_from_state<
       T: 'static + AsLogicalPlan,
       U: 'static + AsExecutionPlan,
   >(
       scheduler: SchedulerGrpcClient<Channel>,
       concurrent_tasks: usize,
       session_state: &SessionState,
   ) -> Result<()> {
   ```
   
   And optional parameter in `executor/src/executor_process.rs`:
   
   ```rust
   pub struct ExecutorProcessConfig {
       ...
       /// SessionState which will be used to configure executor
       /// if not provided system will configure itself from 
       /// sensible defaults
       pub session_state: Option<SessionState>,
   }
   ```
   
   **Describe alternatives you've considered**
   A clear and concise description of any alternative solutions or features 
you've considered.
   
   **Additional context**
   
   - Follow up commit would remove `with_object_store_registry` and 
`BallistaObjectStoreRegistry` giving user ability to plug their own and 
removing chunk of code from maintenance.
   - Config extension would be possible
   
   depends on #1096
