Use Cases

Three industries. One engine.

Real deployments with before/after throughput numbers. No synthetic benchmarks.

Signal stress-testing before market open

Hedge fund managers run 50,000 scenario simulations in the 30 minutes before the NYSE bell rings.

Before: Kafka Streams

47min / run

After: Pulse

2.8min / run

"We went from running 3 scenarios to 127 before open. Alpha decay is now a choice, not a constraint."

Marcus ThielHead of Quant Research, Meridian Capital

Pulse ingests tick data from 14 exchanges simultaneously, applies 200+ factor models in parallel, and outputs ranked signal strength with p99 < 1.2ms. Pre-market stress tests that took 47 minutes now complete in under 3 minutes — enough time to act on what you find.

"The root cause was a single misconfigured DSP timeout. Pulse showed us the exact request chain in 4 seconds flat."

Priya KrishnamurthyPrincipal Engineer, BidStream Labs

Pulse correlates bid request logs, auction outcomes, and DSP response times across 12 billion daily events. When latency spikes, the anomaly detection engine pinpoints the offending request chain within seconds — not hours of log digging.

Watching 10,000 sensor feeds for the one anomaly

IoT platform leads monitoring turbine sensor arrays across 47 wind farms for the vibration signature that precedes catastrophic failure.

Before: Spark Streaming

22s detection lag

After: Pulse

0.6s detection

"We caught a bearing failure signature 18 minutes before it would have taken down a 5MW turbine. That's $2.3M of prevented downtime in one alert."

Lena OkaforIoT Platform Director, NordWind Energy

Pulse processes 10,000+ concurrent sensor streams with sub-second windowed anomaly detection. Vibration, temperature, and RPM data are correlated in real time against 3 years of failure pattern training data. Mean time to detection dropped from 22 seconds to 0.6 seconds.

Architecture

Zero-copy streaming topology

Pulse's ingest layer accepts events from any source protocol — Kafka, Kinesis, Pulsar, gRPC, WebSocket — without serialization overhead. Data flows through the processing DAG without ever touching disk.

Compute Model

NUMA-aware thread scheduling

Each processing core is pinned to a NUMA node, eliminating cross-socket memory access. Query operators are compiled to native code at plan time via LLVM, not interpreted at runtime.

Resilience

Sub-millisecond failover

State is continuously replicated to a hot standby via our custom WAL protocol. If a processing node fails, the standby takes over in under 800μs — imperceptible to downstream consumers.

Scaling

Elastic sharding without repartition storms

Pulse uses consistent hashing with virtual nodes to redistribute load when cluster size changes. Adding a node rebalances 1/N of shards, not all of them. No backpressure, no latency spike.

Zero-Copy Stream Processing at Planetary Scale

Proceedings of the VLDB Endowment · 2025

Chen, W. · Nakamura, R. · Osei, K. · Patel, S.

We present a novel approach to stream processing that eliminates serialization overhead entirely through a shared memory architecture with hardware-enforced isolation. At 50B eps, p99 latency remains below 1.1ms.
