These are some great points, Sean, and the answer is that slouch doesn't take either of those away.
You can use iterator.abort() to stop the iteration, e.g. https://github.com/redgeoff/slouch/wiki/Don't-just-relax.-Slouch!#example-4---continuously-process-all-changes-to-a-db Also, you can get a node stream from the iterator with iterator.toStream(). (For more info see https://github.com/redgeoff/quelle/blob/master/scripts/stream-iterator.js#L149--sorry, documentation is still coming) In the end, this new pattern may not be to your liking, but we've found it to greatly simplify our code. And, you still have options to also keep with existing conventions.
