Fair enough... but somehow your system knew of failed attempts and the need to retry, correct? I'm sure I'm trivializing a rather complicated workflow, but if there's a way to detect failed attempts, there should be a way to remove them from the billing. (perhaps a separate S3 file that can be used to reduce the number of charged attempts, or split the ones you have into 'success' and 'fail' versions?) Oh, and Cassandra is great... used it for years. Just beware of over-sized results. I've seen run-away queries crash the instance(s) running the query; ugly stuff. Glad you found a solution that works!
