Meta's ZGateway Proxy Unifies ZippyDB Client Traffic to Cut Connection Sprawl

Meta has introduced ZGateway, a stateless proxy tier that now carries about 40% of all ZippyDB traffic, projected to exceed 60%, and handles over 1 billion operations per second.

The proxy collapses the many-to-many client-to-database connection mesh into two bounded hops, adding about 6% computational overhead in an average use case.

It also enables admission control, load balancing, and cross-region resilience, which contain reconnection storms that previously caused host crashes.
