Raft in Scylla
Agreement in a distributed system is complicated but required. Scylla gained lightweight transactions through Paxos but the latter has a cost of 3X roundtrips. Raft can allow consistent transactions without the performance penalty. Beyond LWT, we plan to integrate Raft with most aspects of Scylla making a leap forward in manageability and consistency

Empowering the DynamoDB Application Developer with Alternator
Getting started with AWS DynamoDB™ is famously easy, but as an application grows and evolves it often starts to struggle with DynamoDB’s limitations. We introduce Scylla’s Alternator, which provides the same API as DynamoDB but aims to empower the application developer. In this presentation we will survey some of Alternator’s developer-centered features: Alternator lets you test and eventually deploy your application anywhere, on any public cloud or private cluster. It efficiently supports multiple tables so it does not require difficult single-table design. Finally, Alternator provides the developer with strong observability tools. The insights provided by these tools can detect bottlenecks, improve performance and even lower its cost.

Best Practices for Change Data Capture in Scylla
Scylla's CDC is now GA. With it you can build applications that need to collect a stream of changes (optionally with pre/post image). In this session we will review the concepts behind CDC: how data is stored, and how you can query it. In addition we will review best practices for building applications to extract the data using the primitives, and some foundation libraries we are building to assist you.

Scylla Performance Enhancements: Year in Review
The talk will cover most of the performance enhancement introduced to Scylla over the past 12 months. As the throughput was very good before, we focused on Scylla’s behaviour under all types of workloads and data models. Scylla improved its latency under all scenarios, improving the behaviours of data models such as large partitions and time series, improvement of the I/O scheduler and behaviour of streaming and repair.

The All-New Scylla Monitoring Stack
Scylla Monitoring has been enhanced to be a one stop shop to monitor Scylla. To achieve this, scylla-monitoring now includes a CQL interface and log collection analysis. The combination of matrices, alerts, logs & CQL allows not only a single point to view all the information but also to advise you what may be the source of a performance/latency degradation (malfunctioning node).

How We Made Scylla Maintenance Easier, Safer and Faster
Many Scylla maintenance operations require significant data movement between database nodes in a cluster. It is not an easy task to make the management operations efficient while maintaining minimum impact on the workload all the time. In this talk, we will share how we made those maintenance operations easier, safer and faster with the new Scylla features and improvements, e.g., seedless, repair based node operations, smarter off-strategy compaction, io bandwidth limiter for repair and compaction, parallel repair in Scylla Manger and more.
