Modifies the settings for a cluster. For example, you can add
another security or parameter group, update the preferred maintenance window,
or change the master user password. Resetting a cluster password or modifying
the security groups associated with a cluster do not need a reboot. However,
modifying a parameter group requires a reboot for parameters to take effect.
For more information about managing clusters, go to Amazon
Redshift Clusters in the Amazon Redshift Management Guide
You can also change node type and the number of nodes to scale up or down the cluster. When resizing a cluster, you must specify both the number of nodes and the node type even if one of the parameters does not change. If you specify the same number of nodes and node type that are already configured for the cluster, an error is returned.
