Difference b/w Cache Writer and Cache entry listener

In one of my previous blogs, I gave an overview of Cache Loader+Writer as well as Cache entry listeners. The difference b/w a Cache Loader and Cache create/update entry listener is obvious and their roles are clearly differentiated

a loader pulls the value from an external source

populates the cache and

the respective listener is then invoked

There is no question/doubt on whether one can be…

Building the JCache Java EE 8 bridge.. one brick at a time

Let’s quickly look at the Java EE 8-JCache bridge project. This is another concrete step as far as Java EE 8 integration efforts are concerned..

Background

Details on the general idea behind this can be picked up from one of my recent posts on this topic

A bridge ?? What for ?

Serve as the integration point for JCache & Java EE 8

Provide decoupling: the Java EE 8 platform and the JCache API can…

JCache in Java EE 8

The contents of this post are derieved from conversations on the Java EE 8 mailing lists with regards to JCache integration. There are a couple of threads

One initiated by Arjan Tjims and is being continued here

and the other one by Adam Bien

Here are a bunch of points which seemed to have to come out of the discussions so far

JCache & Java EE 8 integration points Managing Caches

The ‘Java Caching’ Refcard is live on DZone !

Happy to announce the availability of the Java Caching Refcard on DZone :-)

The Refcard is not the holy grail of everything related to caching using Java. It primarily focuses on a couple of areas

JCache API foundations: The idea was to give a good enough overview of the JCache API in order to enable developers to get up and running with it quickly

Caching strategies: Discusses some of the common…

JCache (JSR 107) is the Java standard for Caching… enough said. No more introductory stuff.

This is a quick fire post which talks about

Multiple JCache provider configurations, and

Feature: JCache stats via JMX Mbeans

Managing multiple JCache providers

In case you are dealing with a single JCache provider, javax.jcache.Caching.getCachingProvider() returns an instance of the one and only CachingP…

I know you love PurgeCache.sh – even if you don’t, aren’t you curious about what it does ?

Oracle IDM uses OSCache from the OpenSymphony project for in memory caching of objects in order to avoid repetitive calls to database and improve performance (of course !). In case you are not familiar with caching in general, I am pretty sure that as someone working on OIM, you would have executed PurgeCac…

This post covers the JCache API at a high level and provides a teaser – just enough for you to (hopefully) start itching about it ;-)

What is JCache?

JCache (JSR 107)is a standard caching API for Java. It provides an API for applications to be able to create and work with in-memory cache of objects. Benefits are obvious – one does not need to concentrate on the finer details of implementing the…
