    @danny0405 Sorry about the long delay.  I also got rather busy with other things.
    
    My personal choice would be a combination of 1 and 2.  We have run into an issue internally where very rarely where a blob may be uploaded to nimbus as part of submitting a topology and then the blob is deleted before the topology itself can be submitted.
    
    We are likely to fix this by using a variant of 1, something where we give ourselves a few mins after we see a blob with no corresponding topology before we decide it is fine to delete it.  That should fix the issue in 99% of the cases, and also fix the upload issue.
