ScyllaDB vs Cassandra

Scylla and Cassandra are both open-source, distributed NoSQL databases designed to handle large amounts of data across many commodity servers. They are often compared due to their similar data models and use cases.

Scylla offers the horizontal scale-out and fault-tolerance of Apache Cassandra but delivers 10X the throughput.

Scylla achieves the same throughput with a 3-node cluster as a 30-node Cassandra cluster.
