Acunu has developed a new storage stack for big data that bridges the gap between existing database and storage solutions and the demands of massive data. By combining existing tools with its new storage stack designed for big data, Acunu enables real-time Cassandra performance with consistent, reliable and predictable performance out of the box. It allows for fast snapshots, clones, high throughput updates and random reads by exploiting both SSDs and HDDs, providing performance that is up to 100 times better than Apache Cassandra.
