Cache vs. Database: Comparing Memcached and ScyllaDB

ScyllaDB and Memcached take different paths to low-latency performance, yet benchmarks show they can converge under real workloads. Memcached excels at lightweight, pipelined key-value access, while ScyllaDB trades higher per-item overhead for persistence, richer data models, and predictable scaling. The right choice depends on workload shape, data size, and resilience needs.
