10/22/2021, 8:57 PMThat's correct. I forget the terminology, but those resources default to not being deleted when the stack is torn down. If you want that behavior, you need to specify it when creating the resource

@arda once you remove a stack and retain a table, the table becomes orphaned, it doesn’t belong to any stacks.

And when you create a new stack, you can’t tell it to re-use an existing table.

This applies to all AWS resources. You can’t not reuse an existing resource in a new stack.

There is a way around this which is to import an existing resource into a stack - https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resource-import.html
