Writing docs is hard ... You can think of PostgREST as one big pure(ish) function It translates ONE http request to ONE SQL query and executes it in a transaction (after setting some context). There is very little overhead. 90%+ of the time of a request is consumed by the db running the query. So usually, a request is about 5ms-10ms (without network time).
