The technical principles and application practice of the Circumflex Cache framework in the Java class library

Technical principles and application practice of Circumflex Cache framework Overview: Circumflex Cache is a Java class library that provides cache management functions to help developers improve system performance and response speed.This article will introduce the technical principles of the Circumflex Cache framework and provide some practical practice examples. 1. Technical principle: Circumflex Cache uses an efficient hash table data structure to store the cache object based on the concept of memory cache.Its core idea is to cache the frequently used data to the memory, and to speed up the data reading speed through rapid access to memory, avoid repeated calculation and frequent IO operations. Circumflex Cache framework uses key values pair to organize caching data.Each key is unique, and the corresponding value can be obtained through the time complexity of O (1) through the key.When storing the cache object, the Circumflex Cache uses the LRU (Least Recently Use) algorithm for data elimination to ensure the efficiency of memory use. At the same time, Circumflex Cache provides some commonly used cache functions, such as life cycle management, timeout settings, asynchronous loading, etc.These functions allow developers to provide flexible configurations based on specific scenarios to achieve more efficient cache management. 2. Application practice: Next, we will show the specific application practice of the Circumflex Cache framework through some Java code examples. 1. Create a cache object: CircumflexCache<String, Integer> cache = new CircumflexCache<>(); 2. Add cache data: cache.put ("key1", 100); // Cchestrate 100, the key is "Key1" Cache.put ("key2", 200); // Cchestrate 200, the key is "Key2" 3. Get the cache data: int value1 = cache.get ("key1"); // The cache data of the acquisition key is "Key1" int value2 = cache.get ("key2"); // The cache data of the acquisition key is "Key2" 4. Remove the cache data: cache.remove ("key1"); // The cache data of "Key1" is removed 5. Set the cache overtime: cache.put ("key3", 300, duration.ofminutes (30)); // Cchestrate 300, the key is "Key3", set the cache timeout to 30 minutes for 30 minutes 6. Asynchronous loading cache data: CompletableFuture<Integer> future = cache.loadAsync("key4", () -> { // Load the cache data through some operations return 400; }); int value4 = future.get (); // Get the cache data of asynchronous loading Through the above examples, we can see that the use of the Circumflex Cache framework is very simple and flexible.Through reasonable configuration and management cache objects, we can significantly improve system performance and response speed in Java applications. in conclusion: The Circumflex Cache framework is a powerful Java class library. It provides cache management functions based on the concept of memory cache.Through reasonable configuration and use, we can achieve efficient cache management in Java applications and improve system performance and response speed.
