I was surprised by the quality of this one. That said... Cold starts are a FaaS learning subject but they almost never matter much in practice. What workloads are intermittent and also need extremely low latencies? Usually when I see people worrying about this it is because they have architected their system with call chains and the use case, if it really matters, can be re-architected so that the query result is pre prepared. This is much like search results... Search engines certainly don't process the entire web to service your queries. Instead, they pre-calculate the result for each query and update those results as content CRUD happens.
