ZStream: A Cost-based Query Processor for Adaptively Detecting Composite Events

Summary: ZStream uses tree-based query plans instead of NFAs to detect composite events, unifying sequence, conjunction, disjunction, negation, and Kleene closure as join-style operators. A cost model with dynamic programming enables adaptive plan selection and on-the-fly ordering, yielding significant speedups over NFA CEP. (summarized by gpt-5-nano on Feb 09 2026)
