I think update lag is not the biggest issue. Endpoint availability and response times is more important for most of the users, at least short-term. If there's a lag spike that goes away, most users won't even notice (persistent lag is different of course). If however the user's queries time out, that is different.
The problem that I see here is how to quantify what we want. We probably can reasonably promise endpoint availability, as in "can run trivial queries" (even that I would not be sure how to quantify). However, if we get to the "interesting" queries, the variety is so large then I am not sure how to express any guarantees in any certain terms. Maybe p95/p99? But that can be influenced by any random bot...
Do you have any SLOs in mind that we could look at and get an impression how that should look like?
