I'll reply myself...
From the documentation: http://dev.mysql.com/doc/mysql-cluster-excerpt/5.1/en/mysql-cluster-limitations-limits.html
A DELETE statement on an NDB table makes the memory formerly used by the deleted rows available for re-use by inserts on the same table only. However, this memory can be made available for general re-use by performing a rolling restart of the cluster. See Section 7.5, “Performing a Rolling Restart of a MySQL Cluster”.
