**1. Severity of the issue: (select one)**  
 None: I’m just curious or want clarification.

I am looking at the configuration for spilling storage and i came across  
type: ray\_storage which is implemented via: ExternalStorageRayStorageImpl found in file: python\ray\_private\external\_storage.py  
i was wondering what it represents as there is no documentation for this

Hi Shiranbi, this was an experimental API that is in the process of being deprecated. The idea was to configure external storage across the entire Ray cluster, but it was never carried through and I wouldn’t recommend using it.

There is not currently a stable API to disable spilling but we’re in the process of adding one: [[Core] Expose object\_spilling\_enabled Option to Public API by MengjinYan · Pull Request #51851 · ray-project/ray · GitHub](https://github.com/ray-project/ray/pull/51851)
