ScyllaDB Benchmarks

Selecting the right database for your application is an important task. At ScyllaDB we constantly test Scylla against Cassandra for throughput and latency. Database latency determines your application speed, while database throughput defines how many users your application can service. ScyllaDB uses various testing tools such as industry YCSB benchmarks and dedicated Cassandra Stress tests.

4-node Scylla 2.2 (i3.metal) vs 40-node Cassandra 3.11 (i3.4xlarge)

  • 2.5X reduction in AWS EC2 costs
  • Dramatic improvement in availability through 10X reduction in cluster size
  • Up to 11X improvement in 99th percentile latency
  • Amazon EC2 Bare Metal Instances are a great platform for Scylla
ScyllaDB vs. DynamoDB Benchmark

Scylla Cloud beats DynamoDB handily in a wide range of benchmarks

  • 20x better throughput in the hot-partition test
  • Scylla Cloud is 1/7 the expense of DynamoDB when running equivalent workloads
  • Scylla Cloud: Average replication latency of 82ms. DynamoDB: Average latency of 370ms.
  • Scylla provides you freedom of choice with no cloud vendor lock-in

Scylla Cloud performs better and costs less than Google Cloud BigTable

  • Scylla Cloud performs 26X better than Google Cloud Bigtable when applied with real-world, unoptimized data distribution
  • Google BigTable requires 10X as many nodes to accept the same workload as Scylla Cloud
  • Scylla Cloud was able to sustain 26x the throughput, and with read latencies 1/800th and write latencies less than 1/100th of Cloud Bigtable
