+ <literal>NDBCLUSTER</literal> storage engine. Clustering

- In MySQL versions previous to 5.1.6, the
- <literal>NDBCLUSTER</literal> storage engine was strictly
- in-memory; beginning with MySQL 5.1.6, it is possible to
- store Cluster data (but not indexes) on disk. This allows
- MySQL Cluster to scale upward with fewer hardware (RAM)
- requirements than previously. In addition, the Disk Data
- implementation includes a new <quote>no-steal</quote>
- restoration algorithm for fast node restarts when storing
- very large amounts of data (terabyte range). See
- <xref linkend="mysql-cluster-disk-data"/>.
