ScyllaDB High Performance

ScyllaDB is a distributed, NoSQL database that reimplements Cassandra in C++. Unlike Cassandra (Java-based), ScyllaDB runs without the JVM, offering dramatically lower latency and higher throughput while maintaining wire-protocol compatibility with Cassandra. You write CQL (Cassandra Query Language) and use the same driver libraries; ScyllaDB handles the heavy lifting with lock-free design, shared-nothing architecture, and CPU-efficient I/O. ScyllaDB is engineered for the modern era of multi-core processors and cloud-native deployment. It's a drop-in replacement for Cassandra that runs on the same hardware and handles 10–100x more operations per second at sub-millisecond latencies.
