MSK instance size using CDK

Question

According to the CDK documentation (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-msk-cluster-brokernodegroupinfo.html#cfn-msk-cluster-brokernodegroupinfo-instancetype), which is validated by my testing, the smallest broker instance type supported by CloudFormation or the CDK is kafka.m5.large.  My use case does not warrant that large in size, and indeed, one can be created via the console of type kafka.t3.small.  How can I create an MSK cluster of type kafka.t3.small via CF/CDK?

Hi, it seems it's a documentation issue. I just used "kafka.t3.small" in a CloudFormation template and it created a cluster successfully. I already reported the problem.

When I tried using the CDK, the cluster wouldn't stabilize and the deployment failed.  I'll double check, but that seemed to be the problem.

You're right, my mistake, my test worked this time.  Thanks
