Functionality Added or Changed

  • New cluster management client DUMP commands were added to aid in tracking transactions, scan operations, and locks. See DUMP 2350, DUMP 2352, and DUMP 2550, for more information.

  • Added the mysqld option --ndb-cluster-connection-pool that enables a single MySQL server to use multiple connections to the cluster. This enables scaling out using multiple MySQL clients per SQL node instead of or in addition to using multiple SQL nodes with the cluster.
