ScyllaDB Release 2.0

ScyllaDB 2.0, a major release of the open-source NoSQL database compatible with Apache Cassandra, introduces several enhancements aimed at improving performance and usability. This version offers experimental support for Materialized Views, which automates the process of querying the same record by multiple keys, and introduces a row cache feature that significantly boosts performance for large partitions. Additionally, the release includes Heat Weighted Load Balancing to optimize node selection, native support for EC2 i3 instances, and experimental CPU isolation for enhanced latency management. While the update deprecates older Cassandra drivers in favor of those compatible with Cassandra 3.0, it maintains backward compatibility with all ScyllaDB 1.x versions. Users are encouraged to upgrade from ScyllaDB 1.7.4 or later, and to consult the impact and known issues sections before proceeding. Notable fixes and new metrics are also part of this release, alongside improvements for CPU-bound workloads and DNS resolution capabilities.
