How Python Data Engineers Use Falcon

Data engineers use Falcon to build high-performance internal data APIs where raw throughput matters more than developer convenience. Its minimal overhead makes it well-suited for serving ML model predictions or cached pipeline results at low latency — a Falcon endpoint can handle thousands of requests per second on modest hardware.
