> User job is executed in a dedicated thread pool. We return a CompletableFuture to which the user may add more stages. These stages could still be executed in the same Compute dedicated thread pool, so if a follow-up stages of the returned future run some heavy tasks, they can potentially block the job execution thread pool which may be a problem.
