Meta's ZGateway Cuts ZippyDB Connections 19x While Handling 1B+ Operations per Second

Adding a network hop to make a database faster sounds like nonsense, and then you read Meta’s numbers 😄 ZGateway, a stateless proxy in front of ZippyDB, cut per-host connections 97-98% and total persistent connections roughly 19x while carrying over a billion operations per second. Latency improved, because the database nodes stopped burning themselves out on connection management. The bottleneck is rarely where the diagram says it is.
