> The current implementation of the physical query plan uses "thread::spawn" 
> which is expensive. We should switch to using Futures, async!/await!, and 
> tokio so that we are launching tasks in a thread pool instead and writing 
> idiomatic Rust code with futures combinators to chain actions together.
