From the developer:
MySQL Cluster is a write-scalable, real-time, ACID-compliant transactional database. With a distributed, multi-master architecture and no single point of failure, MySQL Cluster scales horizontally on commodity hardware with auto-sharding (partitioning) to serve read and write intensive workloads, accessed via SQL and NoSQL interfaces.
