I am a fresher to Ray, I used to do some works based on Apache Spark. Recently, I found there are some researchers integrating Spark and Ray for distributed machine learning and I am interested in this.
I want to know if the integration of Spark and Ray realized by Spark by opening multiple independent Ray tasks for each Executor, such as the RayonSpark developed by Intel. And what is the benefit for these works？
Can anyone please provide some thoughts on this?
