Engine Capabilities

Massive Concurrency

Process millions of simultaneous events with lock-free scheduling and zero contention. Our engine distributes workloads across all available cores with near-linear scaling.

engine.spawn(1_000_000, EventHandler::new())

Deterministic Replay

Every simulation run produces identical results. Debug complex event cascades by replaying exact sequences, stepping through time with full state inspection.

engine.replay(snapshot, TimeRange::full())

Real-time Streaming

Subscribe to live event streams with sub-millisecond latency. Filter, transform, and aggregate events in-flight without buffering or batch delays.

engine.stream().filter(|e| e.priority > 9)

Fault Tolerance

Automatic checkpoint and recovery ensures zero data loss. The engine survives node failures, network partitions, and cascading errors without manual intervention.

engine.config().resilience(Level::Maximum)

Distributed Topology

Deploy across clusters, regions, and cloud providers. The engine automatically discovers peers, balances load, and maintains consistency across distributed nodes.

engine.cluster().join("us-east", "eu-west")

Time Warping

Accelerate or decelerate simulation time without losing precision. Run years of simulated events in seconds, or slow down to inspect individual event interactions.

engine.time().warp(Factor::x1000)

Performance at Scale

0 Events / Second
0 % Uptime SLA

Get Started

main.rs
use concengine::{Engine, Config, EventHandler};

fn main() {
    let engine = Engine::builder()
        .concurrency(1_000_000)
        .resilience(Level::Maximum)
        .topology(Topology::Distributed)
        .build();

    engine.on_event(|event| {
        // Process each event deterministically
        event.transform().emit()
    });

    engine.run_forever();
