Intel Optane and ScyllaDB: Providing the Speed of an In-memory Database with Persistency

Vladislav Zolotarov's blog post explores the combination of ScyllaDB and Intel Optane SSD DC P4800X drives to achieve the performance of an in-memory database while addressing cold-cache and data persistence challenges. The experiment involved testing various scenarios using three ScyllaDB servers and three client servers, with impressive results in terms of latency and throughput. Using tools like Diskplorer and cassandra-stress, the study found optimal concurrency points and demonstrated ScyllaDB's ability to fully utilize infrastructure for high-throughput, low-latency workloads. The findings revealed that Intel Optane provides great latency results and is more cost-effective than traditional DRAM or Enterprise SSD configurations, achieving similar performance to all in-memory databases without compromising on essential metrics such as throughput, latency, and performance.
