Paul Lappas: The fact that using AWS Lambda (to push Redshift data into Cloudwatch) guarantees "at least once" semantics versus our assumption of "exactly once". This means that your application needs to support the possibility that the Lambda job will run more than once with the same message body and inputs. This fact is not documented well and so it took us a bit to figure out what was happening.
