# Managing Amazon DocumentDB cluster parameter groups
<a name="cluster_parameter_groups"></a>

You can manage Amazon DocumentDB engine configuration by using parameters in a cluster parameter group. A *cluster parameter group* is a collection of Amazon DocumentDB configuration values that make it easier to manage the parameters of your Amazon DocumentDB clusters. Cluster parameter groups act as a container for engine configuration values that are applied to all instances in the cluster. 

This section describes how to create, view, and modify cluster parameter groups. It also shows how you can determine which cluster parameter group is associated with a given cluster.
