Working with Cluster Performance Data
You can work with cluster performance data using the Performance, Queries, and Loads tabs. For more
information about working with cluster performance, see Working with Performance Data in the Amazon
Redshift Console (p. 183).
Managing Clusters Using the AWS SDK for Java
The following Java code example demonstrates common cluster management operations including:
• Creating a cluster.
• Listing metadata about a cluster.
• Modifying configuration options.
After you initiate the request for the cluster to be created, you must wait until the cluster is in the available
state before you can modify it. This example uses a loop to periodically check the status of the cluster
using the describeClusters method.When the cluster is available, the preferred maintenance window
for the cluster is changed.
