Wildfly 10 - Infinispan configure local cache with storeAsBinary option

[francesca.herpertz]

Hi all together,

I was trying to configure jboss using a local cache with the option enabled - "store as binary". As described here https://issues.jboss.org/browse/ISPN-5657 it seems it is not supported in any version of wildfly so far.

I came across the following stack overflow question: http://stackoverflow.com/questions/21490744/how-to-set-up-wildfly-as-with-infinispan-6-0  This gave me the idea to configure the standalone.xml like described above. Setting the "storeAsBinary" property on the standard SingleFileStoreConfigurationBuilder does not work. The Builderclass responsible does not have a setter specified for storeAsBinary. This xml snipped will try to call a method "setCallAsBinary(param)" which is not available on any of the CacheStoreBuilder Classes. The programmatically way to configure this would be - Builder.storeAsBinary().enable(). 

Then I tried the following - I created my own wrapper class CustomSingleFileStoreConfigurationBuilder which extends the SingleFileStoreConfigurationBuilder and gave it the required setter to set the storeAsBinary property via the above mentioned XML. 

Basically I followed this article to create my own builder class etc.:

https://developer.jboss.org/message/934154#934154

Linked examples:

https://github.com/infinispan/infinispan/tree/master/server/integration/testsuite/src/test/java/org/infinispan/persistence/cluster

Although my classes and annotations are configured like shown in the example above - I still get the following error message:

12:04:09,222 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 44) WFLYCTL0013: Operation ("add") failed - address: ([

    ("subsystem" => "infinispan"),

    ("cache-container" => "metaData"),

    ("local-cache" => "metaCache"),

    ("store" => "custom")

]) - failure description: "WFLYCLINF0010: com.package.name.infinispan.CustomSingleFileStoreConfigurationBuilder is not a valid cache store"

I have placed the newly created configuration builder etc. classes in a global module which is configured like this:

<global-modules>

                <module name="com.package.name.config" slot="main"/>

  </global-modules>

I added the cache store like this to my infinispan subsystem:

            <cache-container name="metaData">

                <local-cache name="metaCache" jndi-name="java:/some_cache/MetaCache">

                    <locking concurrency-level="3"/>

                    <transaction mode="FULL_XA" locking="OPTIMISTIC"/>

                    <eviction strategy="LIRS" max-entries="10000"/>

                    <store class="com.package.name.infinispan.CustomSingleFileStoreConfigurationBuilder">

                        <property name="storeAsBinary">

                            true

                        </property>

                    </store>

                </local-cache>

            </cache-container>

But it does not seem to work. I could not find any additional information concerning this matter. What is the correct way to specify a cache store and what makes a cache store valid? Could you perhaps help me to figure out what I am doing wrong?

Thank you very much already and kind regards,

Francesca

Can you elaborate on your need for storeAsBinary?

To answer your specific question, you can configure your cache-container to load classes from a specific module:

e.g.

<cache-container name="metadata" module="com.package.name.config">
 <!-- ... -->
</cache-container>
