If you have a tolerance for video, I'd recommend the bootcamp [1]. Otherwise the tutorial [2]. I'm not familiar with all of the systems you mentioned, but I'd think of it more as a Spark or Dask or MPI competitor and less as a job scheduler. We have tasks, the runtime automatically identifies dependencies between tasks based on what data they use, and the support for describing different partitionings of data is very expressive.
