Agamotto: Scheduling of Deadline-Oriented Incremental Query Execution under Uncertain Resource Price
Summary: Schedules deadline-driven incremental query execution under stochastic, time-varying resource prices instead of fixed trigger frequencies. Agamotto models price uncertainty with an MDP and makes online cost-aware scheduling (supports dependent query workflows), nearing prophet optimality. (summarized by gpt-5-mini on Feb 09 2026)
