Handler takes a long time to complete...?

Hi

I have created a resource in Java and successfully implemented it and it is working. However just to give more context, my custom resource creates a cloudhsm cluster and in the create handler I implement logic to wait for the cluster to be created using callback context as per documentation. But what I experience is that the Cloudformation resource takes a long time before it reaches the complete state. Attached is a cloudwatch log when the create has finished:

Notice the last line where the actual resource has been signalled as completed around 22:21 almost 10 minutes after the 22:12… Why does it writes out twice:

Record handler progress

And why does it take so long time for the second line to be written?. I can see that my resource is stuck in progress state until the second line has been written in cloudwatch logs.

The actual cloudhsm cluster only takes 4-6 minutes to complete. So what is it waiting for even when my code has returned success state once the cloudhsm cluster has been created?

After looking at the stack, it looks like the delay is caused by our backoff when polling the status of the resource. The length of the backoff is a bug on CloudFormation’s side that is currently being addressed

Fix should be deployed out. Going to close this out. If you still see the issue feel free to reopen!
