redis内存回收

1

如redis-内存回收和内存共享部分所描述： 因为c语言不具备自动内存回收功能，**当将redisObject对象作为数据库的键或值而不是作为参数存储时**其生命周期是非常长的，为了解决这个问题，Redis自己构建了一个内存回收机制，通过redisobject结构中的refcount实现.这个属性会随着对象的使用状态而不断变化。 1、创建一个新对象，属性初始化为1 2、对象被一个新程序使用，属性refcount加1 3、对象不再被一个程序使用，属性refcount减1 4、当对象的引用计数值变为0时，对象所占用的内存就会被释放 其中不太理解如何进行这种基于refcount的引用计数回收，对于过期的数据进行的是定期删除和惰性删除，当内存要溢出时进行的是淘汰机制（noeviction、volatile-lru等），但是文中所描述的这种引用计数的回收方式在何时进行呢？
