Meta introduced ZGateway, a stateless proxy tier for ZippyDB that unifies client traffic, enables admission control, load balancing, cross-region resilience, and richer operations. It handles over 1 billion operations per second and carries about 40% of all ZippyDB traffic, projected to grow past 60%, while adding only about 6% computational overhead.
