Streaming Synthetic Data Generators for Stress-Testing Clusters
Introduction
Production stress-testing—pushing systems to capacity to identify failure modes—is risky on live trading infrastructure. Synthetic data generators produce realistic market data with configurable characteristics (volatility, price movements, order frequencies) enabling safe stress-testing of ML pipelines and trading infrastructure without real capital risk.
Synthetic Data Generation
Use statistical models (GAN, VAE) trained on historical market data to generate synthetic tick data indistinguishable from real data. Parametrize generators: volatility regimes, trend directions, correlation structures. Generate synthetic scenarios: normal market conditions, flash crashes, volatility spikes. Stream to testing infrastructure.
Stress-Testing Applications
Verify ML pipeline handles peak throughput (10,000 ticks/second). Test failure modes: dropped data, lagged computation. Validate monitoring/alerting: detect anomalies in synthetic scenarios. Load-test infrastructure without risking real money.
Conclusion
Streaming synthetic data generation enables safe, comprehensive stress-testing of trading infrastructure.
