The ep-core-caching module provides three out-of-the-box application caches to improve performance. These caches are available to both storefront and cortex.

The table below lists the three caches and their default timeout values in seconds:

Core caches are configured via the settings framework. There are three settings for each cache: timeToIdle, timeToLive, and maxEntriesLocalHeap.

For example, to change the timeToIdle and timeToLive values for the category cache to 5 minutes, change the values of the COMMERCE/SYSTEM/CACHING/CATEGORY/timeToLive and COMMERCE/SYSTEM/CACHING/CATEGORY/timeToIdle settings to 300. Note that the changes will not take effect until the application is restarted. For details on how to change these system settings, see Configuring System Settings.

Core caches have a corresponding "lookup" bean declaration in ep-core/src/main/resources/spring/service.xml. By overriding these beans in the following way, you can disable a core cache. For example, to disable the category cache, replace the categoryLookup bean definition:

<bean id="categoryLookup" class="com.elasticpath.commons.beanframework.SwitchableProxyFactoryBean">
	<property name="proxyInterface" value="com.elasticpath.service.catalog.CategoryLookup"/commerce-legacy/>
	<property name="proxy" ref="categoryLookupProxy"/commerce-legacy/>
</bean>

with:

<alias name="nonCachingCategoryLookup" alias="categoryLookup"/commerce-legacy/>
