I started with Amazon Personalize yesterday with the help of this tutorial. Since it took more time than expected, in the middle of the notebook I decided to postpone it and deleted all resources (Cloud Formation stack, Jupyter notebook, S3 Bucket). Evidently, something went wrong. I still have a Dataset Group with status 'Active'. I cannot delete it, because there is one Batch Inference job with status 'Create in progress'. It has this status since yesterday, now for more than 12 hours.
How can I delete all of this? What charges should I expect?
