Modifying the WLM Configuration
The easiest way to modify the WLM configuration is by using the Amazon Redshift management console. You can also use the Amazon Redshift command line interface (CLI) or the Amazon Redshift API.
For information about modifying WLM configurations, see Configuring Workload Management in the Amazon Redshift Cluster Management Guide
You might need to reboot the cluster after changing the WLM configuration. For more information, see WLM Dynamic and Static Configuration Properties.
