ScyllaDB vs Cassandra: 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.

YCSB Benchmark: Scylla vs Cassandra Using Only 3 Scylla Nodes

  • Scylla reduced server footprint by 90%

  • Scylla’s 3 nodes 99th percentile latencies are lower than 30 Cassandra nodes

  • Cassandra servers stall at high ingest throughput rate

  • Applications requiring stable and predictable latency will find Scylla outperform Cassandra
