Scylla is a drop-in Apache Cassandra and Amazon DynamoDB alternative big data database that powers your applications with ultra-low latency and extremely high throughput.

We reimplemented Apache Cassandra from scratch using C++ instead of Java to increase the raw performance and utilization of modern multi-core servers and minimize the overhead to DevOps. We then added our Alternator API, enabling you to run your Amazon DynamoDB workloads anywhere and at a much lower cost.
