Apparently there's a limit to how many API endpoints you can deploy in a second using CDK. Thanks for not having an error message that says that and wasting two weeks.

That's actually commonly known.

From my understanding CDK uses the external APIs to deploy with. This is how Amazon has ensured scalability and unified customer experience.

Imagine running an AWSCLI command for every piece of infra you want to deploy.

Terraform transpiles to cloudformation and is executed just like a CF template within your account. Thus no limiting factors.

If your project is large enough to give you this much trouble, you should think about migrating to terraform or cloudformation.
