Comment 2 for bug 1167056

Thanks for the excellent summary Peter.

What does incrementing by 1 and mul/mod buy us? More runway before needing a reset?

The upgrade procedure you proposed sounds about right: drop, scan for max, and recreate. Care will need to be taken with reusing the index (i.e. a new one and deprecate the old is probably simpler), but that's just details.

As far as the API, I would propose an "opt-in" for the live value. Something like update() return void and add a new updateAndGetLive() that is documented as such.
