缓存老化 meaning in English
cache aging
Examples
- Sql server 2005 ages old , unused plans out of the cache only when space is required
只有当需要空间时， sql server 2005才使旧的未用计划从缓存老化掉。 - Because the age field is incremented every time an object is referenced , frequently referenced objects do not have their age fields decremented to 0 and are not aged from the cache
因为每次引用对象时其年字段都会增加，所以经常被引用的对象的年字段不会减为0 ，也不会从缓存老化掉。
