> Out of interest why do you call this approach "Pessimistic"? That to me means it's doing it badly/in a naïve way. Terms established in the scheduling theory: Optimistic scheduling refers to planning based on the best-case scenario assumptions. Pessimistic scheduling is based on the worst-case scenario assumptions. Stated simply, being _pessimistic_ means we don't trust the mercy of random and iterate until we find enough TIs. Unlike _optimistic_ where we fire a query and expect a good outcome on average. It's a tradeoff between computation intensity and relying on fortune. -- This is an automated message from the Apache Git Service.
