Thanks for the pull request @marshall007. I think this is your first C++ PR? :-)

I'll take a look at it later.

I added a few comments, but looks good mostly.

Are you planning to add support in the other drivers as well? We can take over that part if you prefer.

Just saw that there was some discussion in #3148 on whether this option should be called stride or step. I personally like step better. I'll ask a few people around here for what they think on Monday.

@danielmewes yep! :D I've made updates based on your comments and refactored all those separate optarg checks in the JS driver into util.isPlainObject(obj). I replied to your comment regarding the behavior when step == 0. Just let me know if you think we should support that.

Would be great if someone else could take over, thanks!

Thanks for updating the PR and for the isPlainObject refactor.

Let's keep disallowing step == 0. It avoids potentially unexpected behavior and allowing something later is always easier than the other way around (with respect to backwards compatibility).

The only remaining question is the name of the option. I'll talk to some people to figure this out and let you know later today.

@marshall007 After talking to some people, we settled on step.

The server side of this looks good to me. I haven't reviewed the JavaScript driver changes yet.

@danielmewes sweet! I went ahead and updated the Python driver too.

What's left is to do the Ruby and Java drivers. Working on that now...

Edit: Actually, I don't think people would like more new stuff getting pushed into 2.4. Making this on milestone 2.5.

Pointing this at v2.4.x in preparation for making that branch the main branch of the repo. I intend to look at this post-2.4.2 release.
