Cases typically move from an initial state, such as New, to intermediate states representing progress of the case.
案例通常从一个初始状态(比如new)开始,依次转移到代表案例处理进度的各个中间状态。
Most optimizations, checkpoint processing (aggregating intermediate results so that recovery actions never need to read the entire log), and "fringe cases" are beyond our scope.
大多数的最优化技术,检查点处理(聚集中间结果以便不需要读整个日志就可以恢复动作)和“边缘案例”超出了我们的范围。
In certain cases, as determined by the optimizer, the intermediate temp table is not required, which is reflected in the plan.
在某些情况下,由于是由优化器决定的,就不需要中间临时表,这会反映在计划中。
