Makes sense. At this moment, aws-neptune does not have L2 constructs. If cloudformation has native support that, we can build a L2 with the support, otherwise the custom resources might be required.

looking in the docs on Cloudformation Neptune, there is not an attribute or class like dynamoDB GlobalTable can help with this either

[triggan]

Amazon Neptune has a feature called Neptune Global Database which allows you to have read-only secondary clusters in separate regions from the primary cluster. At present, this feature does not have CloudFormation support. You would need to use a CustomResource construct to implement this in CDK.
