Accelerating Stream Processing Engines via Hardware Offloading
Summary: FlexStream offloads re-partitioning to hardware and adopts a coupled network-executor model to saturate NIC bandwidth and rethink SPE parallelization. With a lock-free state backend and fast migration it achieves 1.95–3.35× throughput and much lower latency spikes and migration time versus prior SPEs. (summarized by gpt-5-mini on Feb 11 2026)
