The DataFusion Ray project [1] originated in datafusion-contrib and was donated to the Apache DataFusion project in September of last year. There was a period of intense development, primarily driven by a single contributor, during which the project underwent a significant rewrite. Unfortunately, the project has now been abandoned. The last commit was almost four months ago, and the main contributor is now working on a new distributed DataFusion project, which will soon be available in datafusion-contrib.
My opinion is that we should move the DataFusion Ray repository back to datafusion-contrib at this time. I would like to hear thoughts from the community. Thanks, Andy. [1] https://github.com/apache/datafusion-ray
