@Generated(value="jsii-pacmak/1.119.0 (build 1634eac)", date="2025-11-13T16:10:09.573Z") @Stability(Stable) public class CfnSubnetGroup extends CfnResource implements IInspectable, ISubnetGroupRef, ITaggable
Specifies a subnet group.

A subnet group is a collection of subnets (typically private) that you can designate for your cluster s running in an Amazon Virtual Private Cloud (VPC) environment. When you create a cluster in an Amazon VPC , you must specify a subnet group. MemoryDB uses that subnet group to choose a subnet and IP addresses within that subnet to associate with your nodes. For more information, see Subnets and subnet groups .

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.memorydb.*;
 CfnSubnetGroup cfnSubnetGroup = CfnSubnetGroup.Builder.create(this, "MyCfnSubnetGroup")
         .subnetGroupName("subnetGroupName")
         .subnetIds(List.of("subnetIds"))
         // the properties below are optional
         .description("description")
         .tags(List.of(CfnTag.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();
