tustvold opened a new issue, #4626:
URL: https://github.com/apache/arrow-datafusion/issues/4626

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   The logic to optimize a `LogicalPlan` currently lives on `SessionContext`. 
This creates a couple of problems:
   
   * Forces `query_execution_start_time` to be stored on `SessionState` when it 
is a per-query property
   * `DataFrame` ends up calling back to `SessionContext` in order to optimize 
its plans, creating circular coupling between them
   
   **Describe the solution you'd like**
   
   I originally thought we might need to introduce a new per-query container, 
but it turns out `DataFrame` already fits this role nicely, especially 
following the changes in #4624.
   
   **Describe alternatives you've considered**
   
   **Additional context**
