   > What's the ideal design going forward? If the end goal is to create one async task for each partition and let tokio thread pool to manage the parallelism (threads), then I think the proper change we want to introduce should be getting rid of `spawn_blocking` and make read_files fully async.
   
   All our readers are blocking; if we do not run then on `spawn_blocking`, won't they block Tokio's runtime?
