How We Upload Multi-GB Files via REST (Without Blowing Up Memory)

Originally published on Hashnode The Challenge Processing large payloads through REST APIs presents a fundamental challenge: how do you accept, validate, encrypt, and store multi-gigabyte data streams without exhausting server memory or degrading response times? Traditional approaches that buffer entire payloads into memory fail spectacularly when data sizes exceed available heap space. The naive solution of simply increasing memory creates a cascading problem—fewer concurrent requ
