What I find odd about this is there's no mention of all the other engines that must be in the mix powering different types of queries: I have no doubt they're using a little of everything, from scaling key-value to search, vector search, caches... They must be doing summersaults to avoid over-saturating this over-saturated Postgres env... yet only Postgres is discussed here.
