DBClusterParameterGroup

Source: src/AWS/RDS/DBClusterParameterGroup.ts

An Aurora cluster parameter group — cluster-wide engine settings shared by every instance in a DBCluster.

Name, family, and description changes force a replacement (RDS has no modify API for these); tags update in place.

Creating a Cluster Parameter Group

const clusterParams = yield* DBClusterParameterGroup("ClusterParams", {
  family: "aurora-postgresql16",
  description: "Cluster-wide settings for the app database",
});

Attach to a Cluster

const cluster = yield* DBCluster("Cluster", {
  engine: "aurora-postgresql",
  dbClusterParameterGroupName: clusterParams.dbClusterParameterGroupName,
});
