Managing Amazon DocumentDB Cluster Parameter Groups

You can manage Amazon DocumentDB engine configuration by using parameters in a cluster parameter group. Cluster parameter groups act as a container for engine configuration values that are applied to all instances in the cluster. To have custom parameter values for different clusters, create custom cluster parameter groups for different clusters.

Using the AWS CLI

The following AWS CLI code determines which parameter group is governing the cluster sample-cluster.

aws docdb describe-db-clusters \ --db-cluster-identifier sample-cluster \ --query 'DBClusters[*].[DBClusterIdentifier,DBClusterParameterGroup]'

Output from this operation looks something like the following (JSON format).

[ [ "sample-cluster", "custom3-6-param-grp" ] ]
