URL: https://github.com/apache/arrow-datafusion/issues/3264

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   A clear and concise description of what the problem is. Ex. I'm always 
frustrated when [...] 
   (This section helps Arrow developers understand the context and *why* for 
this feature, in addition to  the *what*)
   
   Certain operators (Sort, HashJoin, etc) support spill-to-disk if they have 
to buffer too much data in memory. For some use cases this may not be desired 
and it would be better to have the query fail. 
   
   It would be great if this was configurable in the `SessionConfig` and if the 
flag was set to false, any operator which uses a `MemoryConsumer` would fail 
instead of trying to spill to disk. 
   
   **Describe the solution you'd like**
   A clear and concise description of what you want to happen.
   
   Add an `enable_disk_spill` to the `SessionConfig` (which can default to 
`true` for backwards compat). Current implementations of `MemoryConsumer` 
should respect this flag and fail when `spill` is called if disk spill is 
disabled. 
   
   **Describe alternatives you've considered**
   A clear and concise description of any alternative solutions or features 
you've considered.
   
   This could be configured on a per-operator basis but I think it probably is 
something that needs to be either globally disabled or enabled in the vast 
majority of use cases. 
   
   **Additional context**
   Add any other context or screenshots about the feature request here.
