Scylla shard-aware drivers provide superior performance by connecting clients directly to the exact CPU on the specific node responsible for the data. Our drivers ensure your queries are distributed as evenly and efficiently as possible across the cluster for lowest p99 latencies and highest overall throughput. We’ve also customized our drivers to provide optimal performance for Change Data Capture streams.
Scylla is fully compatible with all Apache Cassandra CQL and Amazon DynamoDB APIs so you can use Scylla as a frictionless replacement. Scylla’s superior design will still provide improved performance over other NoSQL databases using these existing drivers/APIs; connections will just not be as fast or as smoothly distributed as they can be.
Amazon’s DynamoDB database is normally connected to via a single endpoint IP address. Scylla’s Alternator, which serves as a drop-in replacement for DynamoDB, can use the Scylla Load Balancer to distribute requests smoothly across the entire cluster, rather than directing all queries to a single IP address connected to one node.
