Decisioning before the bid window closes.
Real-time bidding gives you ~10ms after the auction call. Profile lookups can't be a round trip.
User profiles, frequency caps, and segment data are scattered across stores. Each lookup adds milliseconds you don't have.
Capabilities that map directly to the pain.
Edge-deployable
Run CortexDB close to the exchange — colo or edge POP — and skip the cross-region penalty.
Columnar hot path
Hot profile attributes served from memory-mapped columnar segments.
Namespace isolation
Advertiser-scoped tenants. One noisy bidder doesn't degrade another.
No cold start
Fluid Compute–style instance reuse. The first request after a deploy is as fast as the millionth.
The architectural decisions that matter here.
Predictable p99
Designed for tail latency, not average.
Backpressure-aware writes
Win logs flow in without stalling reads.
Want to see this running on your data?
Memory at the speed of speech.
Conversational voice agents have a ~200ms latency budget before they sound unnatural. CortexDB delivers full long-term recall inside it.
Determinism for the order book.
Tick data and order events need predictable storage latency — not a query planner that gets cute under load.
High-cardinality storage that doesn't fold under write pressure.
Metrics, traces, and logs at modern scale crush row stores. CortexDB is built for the append-heavy, time-bounded shape of telemetry.
