ScyllaDB is the database for data-intensive applications that require predictable performance at scale (like @Bsky.app)!

We built a #Rustlang driver for ScyllaDB Alternator that achieves ~58% higher throughput than the AWS SDK driver on a 3-node cluster, with low P99 latencies. To measure the performance, we extended our Latte tool to work with DynamoDB API as well as CQL. www.scylladb.com/2026/08/27/n... #ScyllaDB

Building a New Rust Driver for ScyllaDB’s DynamoDB API – with 58% More Throughput

How our new Rust driver load-balances DynamoDB-style requests across a ScyllaDB cluster, and how we extended Latte to measure its performance…

To predict what’s likely to appeal to a reader, Medium processes user activity signals and correlates them with a steady stream of recommendations. But how do they store and retrieve the data to ensure the content is relevant while the user is browsing? www.scylladb.com/2026/08/11/m... #ScyllaDB

How Medium Powers Real-Time Recommendations at 1M OPS

Inside Medium’s move from relational features to list features in its ScyllaDB-based feature store “Keep readers reading” is the not-so-simple goal of Medium’s recommendations system. To predict what’...

When running high-throughput systems on machines with many cores, CPU time spent on low-level I/O handling competes directly with CPU time needed for application-level work. We show exactly what you need to do to improve the system's overall balance. www.scylladb.com/2026/07/22/a... #ScyllaDB

Offloading I/O to Dedicated Cores: An Asymmetric io_uring Backend for Seastar and ScyllaDB

We moved low-level I/O execution off application cores to dedicated networking cores using Seastar’s new asymmetric_io_uring backend. Explore the architecture design, trade-offs, and benchmark results...

Aerospike’s design means provisioning more nodes just to hold empty disk space. Because ScyllaDB keeps a highly optimized RAM-to-disk ratio, you can run the exact same 6 TB workload on two dense nodes instead of eight.

ScyllaDB vs Aerospike, Wide-Column vs. Key/Value

Wide-column flexibility doesn’t have to come at the expense of performance -- see where the two models differ, where each one wins, and why you no longer have to choose
