Build Low-Latency Rust Applications on ScyllaDB

Get practical tips for building high-performance Rust apps for real-time data streaming

During this free interactive workshop oriented for developers, engineers, and architects, you will learn how to:

- Create and compile a sample social media app with Rust
- Connect the application to ScyllaDB (NoSQL data store) and Redpanda (streaming data)
- Negotiate tradeoffs related to data modeling and querying
- Manage and monitor the database for consistently low latencies

If you’re an application developer with an interest in Rust, Tokio, and event-driven architectures this workshop is for you! This is a great way to discover the NoSQL strategies used by top teams and apply them in a guided, supportive environment.

The Database for Gamechangers
“ScyllaDB stands apart...It’s the rare product
that exceeds my expectations.”
– Martin Heller, InfoWorld contributing editor and reviewer
“For 99.9% of applications, ScyllaDB delivers all the
power a customer will ever need, on workloads that other
databases can’t touch – and at a fraction of the cost of
an in-memory solution.”
– Adrian Bridgewater, Forbes senior contributor
