Yes, the initial memory management [proposal](https://docs.google.com/document/d/1BT5HH-2sKq-Jxo51PNE6l9NNd_F-FyyYcyC3SKTnkIA/edit) and [implementation](https://github.com/apache/datafusion/pull/1526) did support cooperative spilling. However, a later [simplification](https://github.com/apache/datafusion/pull/4522) removed that feature. I believe using a shared `FairSpillPool` for comet operators within the same task is a reasonable approach, especially since the memory manager currently only supports self-spilling. Still, I would love to see cooperative spilling return to DataFusion. -- This is an automated message from the Apache Git Service.
