Deleting Stack Not deleting Lambda CloudWatch LogGroup

Question

I am creating a Lambda function and a Log Group for it to control the retention days using Serverless Application Model (SAM), similar to Cloud Formation. Below is the code snippet. However, when I delete the stack, the Lambda function gets deleted, but the Log Group doesn't get deleted, instead it's retention changes to Never Expire.

```
MyLambdaLogGroup:
    Type: AWS::Logs::LogGroup
    Properties:
      RetentionInDays: 3
      LogGroupName: !Sub /aws/lambda/${MyLambdaFunction}
```

How can I ensure that the Cloud Watch Log Group associated with the Lambda also gets deleted on deleting the stack? Can anyone please help with this?

There are some [workarounds here](https://github.com/aws/serverless-application-model/issues/1216) but please pay attention to the race condition caveats mentioned in the thread.

Have you tried [setting a DeletionPolicy](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html)? If you have the Log Group defined in your template, I would expect setting the policy to delete would remove it.
