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. Whilst retaining compatibility with Cassandra tool and data files, ScyllaDB adds self tuning capabilities. IBM Compose for ScyllaDB makes ScyllaDB even better by managing it for you. This includes offering an easy, auto-scaling deployment system which delivers high availability and redundancy, automated no-stop backups and much more. Note: Compose via Bluemix does not give access to the Compose UI at this time, see https://help.compose.com/docs/bluemix-compose-support for more details.
