I've taken this as far as I can by myself. It definitely needs some input from PM and engineering.

@dwdougherty The language is mostly OK or easily fixed. However, I agree with you that this really needs some input from an expert to clarify some points, given that it's quite complicated.

[dwdougherty]

Thank you, @andy-stark-redis! Hopefully somebody from PM and eng., preferably both, will weigh in. 🤞🏻

Hi @adrianoamaral and @raz-mon. This PR still needs to be reviewed by a SME. Hoping one of you can help with that.

@andy-stark-redis: now that @raz-mon (engineering) has reviewed, please re-review and add your approval. Thanks!

Minor glitch plus a couple of suggestions, but basically LGTM. I'll approve to avoid holding you up.

[dwdougherty]

Thanks again, @andy-stark-redis. All suggestions applied.

I'm closing this PR. Because of a large re-org PR that was just merged, it's easier for me just to reissue my changes in a new PR.
