ScyllaDB is a highly performant, in-place replacement for the Cassandra wide-column distributed database. ScyllaDB is written in C++, rather than Cassandra's Java, for better resource usage that can result in ten times better performance in benchmarks. Pricing is based on underlying disk usage. CPU & I/O resources scale with the underlying disk usage. IBM Compose for ScyllaDB makes ScyllaDB even better by managing it for you. Features include auto-scaling deployments, high availability, and automated no-stop backups.
