How To Implement Cache In Java
High performance scalable web applications often use distributed in-memory data caching in the foreground or in place of powerful persistent storage for some tasks. In Java applications it is very common to use in Caching for better performance. But “What is Caching?” A cache is an area of local memory that holds a copy of frequently accessed data that is expensive to retrieve or compute. Examples of such data include the results of a query to a database, disk file, or report. Read: how to implement cache in java
This is a feature of In Memory Cache and the program topqa.info
Contents
- Items will expire based on how long they last.
- Caching will keep the most recently used items if you try to add more then specify the maximum. (apache’s generic collections have an LRUMap, which removes the least used items from a fixed size map)
- For the expiration time of the items we can mark the time of the last hit and in a separate thread delete the items when the lifetime limit is reached. This is great for reducing memory pressure for applications with long waits between accessing cached objects.
- We will also create a test class: topqa.info
