I don’t have much to say about the proposal, other than to say that if an election ever ends up involving syncing up and exchanging data, doing that just in time is probably less than ideal for most of the more common uses cases.
That’s just an aside though. Id be more interested in seeing the proposal connect problems with solutions. My quick read makes me think the goal is some dimension of scale (I’m guessing a lazy dimension, usually no the most common Solr architecture in my experience fwiw). But I don’t see what the problems are for that dimension of scale or how to connect proposals to solutions to the problems. Unless I’m just missing it.
