Creating new caches with default-cache properties using JCache APIs

[akumar3]

Hi,

Can we create new caches using javax.cache.CacheManager such that this cache will inherit properties from the default cache defined in infinispan configuration file?

My infinispan configuration:

<?xml version="1.0" encoding="UTF-8"?>

<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="urn:infinispan:config:7.0 http://www.infinispan.org/schemas/infinispan-config-7.0.xsd"

    xmlns="urn:infinispan:config:7.0">

    <cache-container name="testCacheContainer"

        default-cache="defaultCache">

        <local-cache name="defaultCache">

            <eviction max-entries="32" />

        </local-cache>

        <local-cache name="existentCache">

        </local-cache>

    </cache-container>

</infinispan>

Now following two caches has different 'max-entries' set (verified by putting around 100 values and then iterating through all elements in the cache):

Cache existentCache = cacheManager.getCache("existentCache");

Cache newCache = cacheManager.createCache("newCache", existentCache.getConfiguration(javax.cache.configuration.CompleteConfiguration.class));

existentCache stores at max only 32 elements; whereas newCache does not seems to inherit this limit on cache size.

What you are trying to do is not currently possible since JCache configuration class is so far limited to the configuration that's in the spec. The simplest workaround would be to define your configurations for JCacheManager in XML. If that's not enough, I'd suggest creating a JIRA and see how we can improve it.
