Batch caching processing in Java caching technology

With the rapid development of the Internet, the performance requirements of application systems are getting higher and higher. For large concurrent applications, caching technology is an indispensable part. Among them, Java caching technology is widely used. With the support of caching technology, we can greatly improve the performance of application systems.

In caching technology, there are two commonly used methods: single caching and batch caching. A single cache refers to operating only a single cache at a time, while batch caching refers to operating caches in batches. In the process of using caching technology, we must make full use of batch caching, which can not only improve efficiency, but also reduce cache space usage.

Batch caching processing in Java caching technology generally refers to using a collection as a parameter to store these data in the cache in batches. This avoids the overhead of a single cache operation each time and improves system performance. At the same time, batch cache processing can also reduce cache space occupation and reduce system maintenance costs.

In Java caching technology, we can use some mature caching frameworks, such as Ehcache, Redis, Memcached, etc. These frameworks all provide batch cache processing APIs, which can help us easily implement batch cache processing.

Let’s take Ehcache as an example to introduce how to use batch caching. Ehcache is an open source Java caching framework that can easily cache data in memory or persist it to disk.

First, we need to define an Ehcache cache manager:

CacheManager cacheManager = CacheManager.create();

Next, we need to define an Ehcache cache to store data. Among them, cacheName is the name of the cache, and maxElementsInMemory is the maximum number of elements allowed to be stored in the cache.

Cache cache = new Cache(new CacheConfiguration(cacheName, maxElementsInMemory));
cacheManager.addCache(cache);

Then, we can use the addElements method to add data to the cache in batches. Among them, the parameter elements of type List stores the elements we want to add.

cache.putAll(elements);

If you need to delete data in the cache in batches, we can use the removeAll method. Similarly, the keys parameter of type List stores the cache keys we want to delete.

cache.removeAll(keys);

For common cache operations, such as reading, adding, updating, deleting, etc., Ehcache provides corresponding APIs, which we can select and combine according to our needs. Moreover, Ehcache also supports cache expiration processing very well, which can effectively avoid problems caused by cached data expiration.

If you need to batch process cached data, you can use Element type List or Map as a parameter by calling putAll method adds data to the cache in batches at one time, or uses the removeAll method to delete data from the cache at one time. This can effectively improve the performance and efficiency of the cache system, avoid the overhead of a single cache operation, significantly reduce the occupation of cache space, and improve operating efficiency.

To sum up, batch caching processing in Java caching technology is one of the important means to improve the performance of application systems. In the process of using cache technology, effective use of batch cache processing can improve system operating efficiency, reduce system maintenance costs, and provide strong support for the efficient operation of application systems.
