Scylla’s internal developer conference and hackathon this past year was a lot of fun and very productive. One of the projects we put our efforts into was a new shard-aware Rust driver. We’d like to share with you how far we’ve already gotten, and where we want to take the project next.

The CQL protocol, used both by Scylla and Cassandra, already has some drivers for the Rust programming language on the market – cdrs, cassandra-rs and others. Still, we have rigorous expectations towards the drivers, and in particular we really wanted the following:

Also, it would be nice to have the driver written in pure Rust, without having to use any unsafe code. Since none of the existing drivers fulfilled our strict expectations, it was clear what we have to do — write our own async CQL driver in pure Rust! And the ScyllaDB hackathon was the perfect opportunity to do just that.

After intensive work during the hackathon, we completed the first version of the scylla-rust-driver and made it open-source available here:
