Java cache technology introduction (JCs open-source project) -- index disk backup Cache

The backup cache of the JCS index disk is an optional plug-in. It mainly aims to provide a second-level cache to reduce the cache pressure on the memory. When the memory cache exceeds the maximum value, the cache processing checks whether "disk" backup cache is configured for the storage area. If the index disk backup cache is used, the cache center saves the items deleted from the memory to the disk. Disk Index TheIndexed disk auxiliary cache) is th

001--jcs Getting Started

JCS Getting Started1. OverviewJCS is a sub-project of the Jakarta Project Turbine, which is a composite buffer tool with flexible configuration features. JCS provides memory, hard disk, distributed architecture, build cache server four ways to implement object cache, it is easy to realize the difference of cache customization. The buffer tool is significantly more useful for read operations than write opera

Hibernate iterator JCs Analysis

JCS is an object cache that caches Java objects to Improve the access efficiency of frequently accessed Java objects. JCs accesses an object based on the unique identifier of the object. For example, it can be accessed Based on the hashcode of the object. For hibernate, JCs can be used to cache the query results, so that when the same data is accessed next time,

. Configure (Configfilename); } Else { Cachemgr= Compositecachemanager.Getinstance(); } } ReturnCachemgr; } } The default configuration file of JCS is cache. CCF, this file should be located in the compositecachemanager class package, and JCs provides two methods for customizing the configuration file: setconfigfilename and setconfigproperties. The two definitions are used in getcachemanager () to initiali

Step 5: Use JCS to quickly build a cache Environment

JCS is a subproject of the Turbine project of Jakarta. It is a compound buffer tool. It can buffer objects to memory and hard disk. The expiration time of the buffered object is set. JCS can also be used to build a buffer distributed architecture for high-performance applications. Objects that require frequent access and consume resources each time they are accessed can be temporarily stored in the buffer z

JCS for distributed cache sharing

To make a product and want the product to be distributed, you have to study the distributed cache. There are many open-source projects for caching. Through testing, JCS is the easiest to configure and use, so it is used as the product cache manager. JCS is an open source project of Apache, project URL: http://jakarta.apache.org/jcs/ Steps: 1.

Precautions for using JCs

Note: JCs The JCs object is cached to disk and written only when the cache partition performs the dispose () operation or JVM shutdown, rather than saving one write; If the JCS object is cached on the disk, it may fail to be cached on the disk due to exceptions such as power failure; The ATTR parameter of the defineregion (string name, icompositecacheattr

Java cache system JCs (1) Usage

JCS is an implementation of cache in Java. It supports caching data to the memory or hard disk and setting the effective duration of the cache object. The following JAR packages are required for use: Commons-collections-2.1.1.jar Commons-lang.2.3.jar Commons-logging-1.0.4.jar Concurrent-1.3.2.jar Jcs-1.3.jar Slf4j-api.jar Define the storage object class that implements the serializable interfa

ORG.TINYGROUP.JCSCACHE-JCS Cache Solution

Org.tinygroup.jcscache is the implementation of Org.tinygroup.cache, using JSC as a technology solution for caching. JCS is a subproject of the Jakarta Project turbine. It is a composite buffer tool. You can buffer objects to memory, hard disks. Has buffer object time expiration setting. You can also build a distributed, buffered architecture with JCS for high-performance applications.
