Rust crate closest to Apache Spark?

What Rust crate (or group of crates) gets us closest to Apache Spark ?

The reason I am not giving up Spark directly is that I am unwilling to give up RAII and I really like Rust.

However, I need a way where I am programming an AWS cluster rather than programming a single machine.

What Rust crate (of group of crates) gets us closest to this ?

Consider perhaps Amadeus with Constellation.

There is also Ballista. It is built on top of the Arrow format, and thus leverages SIMD operations, memory alignment, and interoperability with other Arrow implementations.
