I believe so. I suppose I'm asking for an abstraction that makes maintaining the sequence number simple and fails safely in the presence of errors. I'd basically like to be able to map messages from one topic to another with a guarantee that none of those messages will be lost; even when some error occurs (either a programming error, system downtime, or network partitions). I'd prefer the application to stop producing messages than lose any of them. It sounds like that is possible with Tank so I may end up giving it a try.
