// 功能描述
// 这是基于Redis的定时任务调度器,能够有效的在服务集群里面调度任务,避免了单点压力过高或单点故障问题
// 由于所有的服务代码是一致的,也就是一个定时任务将在所有的服务都有注册,具体调度到哪个服务运行看调度结果

开发目标
# 功能支持
1. 支持单机定时
2. 支持集群定时
3. 支持间隔定时
4. 支持固定时间
5. 支持全局唯一
1. 支持本地任务
2. 支持集群任务
3. 支持单次任务
# 功能说明
设计思想
1. 不再单独区分单机还是集群,统一按集群处理,单机只是集群里面只有一个节点
2. 计算和执行分离,计算只负责计算,执行只负责执行,计算和执行之间通过消息队列进行通信
# 功能实现
1. 集群间任务调度和任务的唯一依赖于redis进行实现
# 缺陷
1. 集群部署时,存在新旧的代码混合问题,任务调度可能存在问题(需要根据实际需要进行版本上线/下线操作)
## 方案一
1. 启动的时候定时向redis注册任务项
2. 每次计算执行时间的时候根据注册的任务项进行任务计算
3. 注册任务项需要有下线机制,避免能运行它的节点下线了它还被执行
现在有根据要求根据系统时间整点运行任务的要求,这个比简单的定时重复更复杂,因为不但要按时执行,并且不能重复执行,需要全局记录任务执行的状态,由于任务的间隔时间不确定,这个任务执行状态的保存周期也是有变化的
