If you haven’t attended a ScyllaDB virtual conference before, be prepared – this isn’t your typical virtual conference that inflicts death by PowerPoint. It’s highly interactive, including the ability to engage with speakers during their sessions and continue the conversation afterward. There will also be contests, opportunities to connect with your peers from around the world, the announcement of this year’s ScyllaDB Innovation Award winners, and more.
Throughout both days, our tech experts will be available to answer your questions in the ScyllaDB lounge. If you’re a ScyllaDB open source user, this is a great opportunity to get your top questions addressed!
This year’s ScyllaDB Summit agenda features talks across a broad array of topics related to data-intensive applications – NoSQL, SQL, event streaming, Rust, WebAssembly, and more. Here’s a spotlight on the slice of sessions that are geared specifically toward ScyllaDB users and the “ScyllaDB curious.”

Raft After ScyllaDB 5.2: Safe Topology Changes
Konstantin Osipov, ScyllaDB
ScyllaDB’s drive towards strongly consistent features continues, and in this talk I will cover the upcoming implementation of safe topology changes feature: our rethinking of adding and removing nodes to a ScyllaDB cluster.
Quickly assembling a fresh cluster, performing topology and schema changes concurrently, quickly restarting a node with a different IP address or configuration – all of this has become possible thanks to a centralized – yet fault-tolerant – topology change coordinator, the new algorithm we implemented for Scylla 5.3. The next step would be automatically changing data placement to adjust to the load and distribution of data – our future plans which I will touch upon as well.
Squeezing the Most Out of the Storage Engine with State of the Art Compaction
Raphael S. Carvalho, ScyllaDB
Log Structured Merge (LSM) tree storage engines are known for very fast writes. This LSM tree structure is used by ScyllaDB to immutable Sorted Strings Tables (SSTables) on disk. These fast writes come with a tradeoff in terms of read and space amplification. While compaction processes can help mitigate this, the RUM conjecture states that only two amplification factors can be optimized at the extent of a third. Learn how ScyllaDB leverages RUM conjecture and controller theory, to deliver a state-of-the-art LSM-tree compaction for its users.
Optimizing ScyllaDB Performance via Observability
Amnon Heiman, ScyllaDB
ScyllaDB already does a great job at basic performance optimization at install time and run-time, with IO tuning for your SSDs and real-time dynamic IO and CPU scheduling. Yet there’s more that you, as a user, can do by observing ScyllaDB’s operations. Learn how to get the most out of your database by using these open source tools, techniques and best practices.
Building Next Generation Drivers: Optimizing Performance in Go and Rust
Optimizing shard-aware drivers for ScyllaDB has taken multiple initiatives, often requiring a complete rewrite from scratch. Learn the work undertaken to improve the performance of ScyllaDB drivers for both Go and Rust, plus how the Rust code base will be used as a core for drivers with other language bindings going forward. The session highlights performance increases obtained using techniques available in the respective programming languages, including shaving performance off Google’s B-tree implementation with Go generics, and using the asynchronous Tokio framework as the basis of a new Rust driver.
Retaining Goodput with Query Rate Limiting
Piotr Dulikowski, ScyllaDB
Distributed systems are usually optimized with particular workloads in mind. At the same time, the system should still behave in a sane way when the assumptions about workload do not hold – notably, one user shouldn’t be able to ruin the whole system’s performance. Buggy parts of the system can be a source of the overload as well, so it is worth considering overload protection on a per-component basis. For example, ScyllaDB’s shared-nothing architecture gives it great scalability, but at the same time makes it prone to a “hot partition” problem: a single partition accessed with disproportionate frequency can ruin performance for other requests handled by the same shards. This talk will describe how we implemented rate limiting on a per-partition basis which reduces the performance impact in such a case, and how we reduced the CPU cost of handling failed requests such as timeouts (spoiler: it’s about C++ exceptions).
