MySQL Cluster Plugin  This plugin automates the configuration
and startup of a MySQL Cluster on StarCluster.  Configuration
Options  To use this plugin add the following to your
StarCluster config file: file:  [plugin mysqlcluster]
setup_class = starcluster.plugins.mysql.MysqlCluster
num_replicas = 2 data_memory = 80M index_memory = 18M dump_file
= test.sql dump_interval = 60 dedicated_query = True
num_data_nodeS = 2  NUM_REPLICAS: Specifies number of replicas
for each table in the cluster, as well as the number of node
groups. The maximum value is 4, and only values 1 and 2 are
currently supported by MySQL. A value of 1 would indicate that
that there is only one copy of your data. The loss of a single
data note would therefore cause your cluster to fail, as there
are no additional copies of that data. The number of replicas
must also divide evenly into the number of data nodes. ‘2’ is
both the recommended and default setting for this parameter.
DATA_MEMORY: Amount of space (in bytes) available for storing d
