Reactors: A Case for Predictable, Virtualized Actor Database Systems

Summary: Proposes reactors, a relational actor model for in-memory OLTP with serializable application calls and intra-transaction parallelism. ReactDB enables flexible virtualization from shared-nothing to shared-everything, with asynchronous execution and low overhead for latency control. (summarized by gpt-5-nano on Feb 09 2026)
