Session state without the Redis tax.
Leaderboards, matchmaking, and player profiles need millisecond reads and durable writes — usually solved with two systems duct-taped together.
In-memory caches are fast and lossy. Durable stores are safe and slow. Most teams run both and reconcile by hand.
Capabilities that map directly to the pain.
p99 < 1ms reads
Embedded path for hot session state.
Durable by default
WAL-backed writes — no "oops we lost the last 30 seconds of progress."
Per-player namespaces
Profile, inventory, and progression scoped without cross-tenant scans.
The architectural decisions that matter here.
One system, not two
Cache and source of truth in the same engine.
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.
Decisioning before the bid window closes.
Real-time bidding gives you ~10ms after the auction call. Profile lookups can't be a round trip.
