At that point you really want to front all database access via a service otherwise it's calling for other problems with schema management, security, resource quotas etc. You can even have separate pools for different use cases like reporting if you don't want a separate server. But each pool really doesn't need more than like 5 connections, even with multiple pools and multiple replicas of your service it will rarely add up to the hundreds.
