Scylla Performance Enhancements: Year in Review

The talk covers most of the performance enhancements introduced to Scylla over the past 12 months. As the throughput was very good before, we focused on Scylla’s behavior under all types of workloads and data models. Scylla improved its latency under all scenarios, improving the behaviors of data models such as large partitions and time series, improvement of the I/O scheduler and behavior of streaming and repair.
