-  拿到一个任务后计算下一次任务下发的时间，将时间戳作为分数，将任务作为内容存入redis的zset中。调度任务会有每秒执行一次并且使用分布式锁的定时任务，从zset中循环取出分数最低的一条判断是否应该被执行，如果需要被执行，将任务推入list队列中并从zset中移除。有另外的定时任务通过订阅队列获取到动作并执行，如果是任务下发动作，那么在执行完成后需要计算下一次任务结束的时间并加入zset中，如果是任务结束动作，同样需要计算下一次任务开始执行的时间并加入zset。
+  拿到任务后，计算任务下一次下发时间和终止时间,将时间戳作为分数，将任务作为内容分别存入下发动作和终止动作的zset中。有两个定时任务每隔5秒执行一次，每次取出分数最小的动作判断是否应该被执行，如果需要被执行，并且是下发动作，寻找到可用的VAServer，执行下发动作，成功后将任务和VAServer进行关联，并将动作从zset中移除。如果是终止动作，寻找到与任务关联的VAServer，执行终止动作，成功后解除关联，并将动作从zset中移除，计算下一次任务下发时间和终止时间，加入zset中。
