Auto-Sharding
MySQL Cluster is implemented as a distributed, multi-master database with no single point of failure. tables are automatically sharded into ss a pool of low cost commodity nodes, enabling the database to scale horizontally to serve read and write-intensive workloads, accessed both from SQL and directly via NoSQL APIs (memcached, REST/HTTP, C ++, Java, JPA and LDAP ). up to 255 nodes are supported, of which 48 are data nodes. you can read more about the different types of nodes here.
