Styx: Transactional Stateful Functions on Streaming Dataflows
Summary: Styx is a dataflow-based SFaaS runtime enabling serializable transactions on stateful functions with arbitrary call-graphs and exactly-once guarantees. Key ideas: boundary acknowledgment, execution caching, and early commit-reply to cut latency; 10x throughput and near-linear scaling on YCSB, TPC-C, DeathStar.
