Every SMS routed requires 6–12 state lookups: opt-out lists, carrier rules, throughput limits, campaign compliance, delivery status. Every IoT device command requires device state, firmware version, connectivity status, last heartbeat. At 1–10ms per Redis read, state lookups become the bottleneck at scale. Cachee serves them all from L1 at 17ns.
An A2P message arrives. Before it reaches the carrier, the platform must check opt-out status, campaign compliance, carrier routing, throughput throttle, and more. Watch how state read speed affects total message latency.
