ehcache vs memcached

EHCache cache for Hibernate performance optimization, hibernateehcache Compared with JDBC operations, ORM frameworks such as Hibernate require more complex mechanisms for ing and object state management. Therefore, there is a certain loss in performance and efficiency. Besides ensuring that ing is avoided to produce inefficient SQL operations, cache is one of the keys to improving Hibernate. Adding cache can avoid connection creation and destruction,

Memcached's distributedAs described in the 1th time, memcached is called a "distributed" cache server, but there is no "distributed" functionality on the server side. The server-side only includes the memory storage features introduced in the 2nd and 3rd times, and its implementation is very simple. As for the distribution of memcached, it is fully implemented by the client library. This distribution is the

scope also has data synchronization issues, so use it with caution. The persistence layer of various cache processing processes can provide multiple caches. If no data is found in the cache of the transaction range, you can also query it in the cache of the application range or cluster range. If no data is found, you can only query it in the database.The principle of using second-level cache:◆ Data will not be modified by a third party◆ The same data system is often referenced◆ The data size is

when we do not specify a CacheManager level of maxbyteslocalheap, we must specify MAXBYTESLOCALHEAP or Maxentrieslocalheap on each cache.maxbyteslocaloffheap is the maximum number of bytes of non-heap memory that can be used to limit the cache, and its units can be k, m, or G. The default is 0, which means no limit. But when we specify maxbyteslocaloffheap at the CacheManager level, we implicitly make all cache levels overflowtooffheap true. Using this property at the cache level only causes th

Ehcache is a cache framework used to configure and manage cache. We analyze from its ehcache. xml file how it inserts data into memory and hard disk.

First, IntroductionEhcache is an open source, pure Java in-process caching framework. It is fast, simple, with a variety of caching strategies and other characteristics. Ehcache is used by default in Hibernate. Using Ehcache in our applications can quickly improve the performance of your application. Ehcache is primarily intended for general purpose caches, Java
