MySQL Cluster is the combination of MySQL with NDB, and NDB itself is a shared-nothing clustered database that keeps running when individual nodes fail and that scales out, with performance improving – both for reads and for writes – as nodes are added. Besides the SQL access available through the MySQL server, a number of high-performance NoSQL interfaces are available that communicate directly with the NDB data nodes. We will discuss the ClusterJ object relational mapping layer for MySQL Cluster and Java, new Memcached API, and the REST & JSON interface mod_ndb.
