ScyllaDB Summit: For the ScyllaDB Curious + Serious Sea Monsters

Note: ScyllaDB Summit has concluded! Watch top tech talks on demand.

If your team is exploring or using ScyllaDB, we hope you’ll join us for a deep dive into the innovations and strategies that will help you get the most out of it. Attend ScyllaDB Summit (free + virtual) on February 15 and 16.


With 2 days of 25+ sessions, this is your chance to quickly:

  • Discover ScyllaDB’s latest innovations for data-intensive applications and learn what’s on the short-term and long-term roadmap
  • Hear how ScyllaDB is being used by engineers at Discord,  Epic Games, Strava, Sharechat & other gamechangers
  • Get the ScyllaDB engineering perspective on topics like serverless, observability, drivers, consistency algorithms, compaction strategies & our DynamoDB API
  • Explore real-world ScyllaDB integrations and best practices: Pulsar, Flink, Ansible, Quarkus, Quine, all-ARM clusters & more

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.

ScyllaDB Summit 2023 Speaker –Kostja Osipov, ScyllaDB, Director Software Engineering


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.

ScyllaDB Summit 2023 Speaker –Raphael Carvalho, ScyllaDB, Software Engineer


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.

ScyllaDB Summit 2023 Speaker –Amnon Heiman, ScyllaDB, Principal Software Engineer


Building Next Generation Drivers: Optimizing Performance in Go and Rust

Piotr Grabowski

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.

ScyllaDB Summit 2023 Speaker –Piotr Grabowski, ScyllaDB, Junior Software Engineer


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).
