ScyllaDB follows a shard-per-core design that assigns specific data partitions to individual CPU cores, reducing internal contention. It employs consistent hashing to distribute data evenly across the cluster and simplifies the process of adding or removing nodes. For reliability, it replicates data across multiple nodes and availability zones. Newer features like ScyllaDB Tablets further enhance this by allowing the database to redistribute data dynamically and scale clusters rapidly in response to traffic spikes.
