-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
