ScyllaDB bypasses the Linux page cache due to its inefficiency for handling database workloads. It utilizes its own row-based integrated internal cache, optimizing memory use, reducing CPU overhead, and improving performance. The cache offers dynamic tuning, eliminates the need for external caches, and supports ScyllaDB's high-performance, latency-sensitive applications.
