The fact that can now be used as a client-server architecture is a game changer. It will for sure replace many data stacks that now run on many servers with tons of cpu and ram
Being able to put it behind an HTTP service / load balancer and implement horizontal scaling based on resource utilization, or even scale to zero via Cloud Run etc. Drool!
Yes! And the server isn't really a server, it's still "in process" so it stays lightweight and simple. This is absolutely fantastic.
