Max object graph size in XML Conf

[Kriss Cardenas]

Hi,

I am using Ecache 3.X and using the JSR API. I want to improve the max-object-graph-size because I have some big objects and I can't find how to write it down in my XML Configuration.

I tried :
max-object-graph-size
and
<sizeOfPolicy maxDepth="10000" maxDepthExceededBehavior="abort"/>

I think maybe JSR doesn't support this, do you have any workaround  other than the @IgnoreSizeOf  tag?

Here's is the last configuration that I tried :

<?xml version='1.0' encoding='utf-8'?>
<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://www.ehcache.org/v3' xmlns:jsr107='http://www.ehcache.org/v3/jsr107'
    xsi:schemaLocation="
        http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.0.xsd
        http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.0.xsd">

    <service>
        <jsr107:defaults default-template="proxyCache" enable-management="false" enable-statistics="false" />
    </service>

    <!-- By reference small cache -->
    <cache-template name="proxyCache">
        <key-type copier="org.ehcache.impl.copy.IdentityCopier">java.lang.String</key-type>
        <value-type copier="org.ehcache.impl.copy.IdentityCopier">com.xxx.xxx.xxx.cADO</value-type>
        <expiry>
            <tti unit="seconds">60</tti>
        </expiry>
        <heap unit="MB">50</heap>
        <max-object-graph-size>10000</max-object-graph-size>
    </cache-template>


    <cache alias="serverCache">
        <key-type>java.lang.String</key-type>
        <value-type>com.xxx.xxx.xxx.cADO</value-type>
        <expiry>
            <tti unit="minutes">5</tti>
        </expiry>
        <heap unit="MB">500</heap>
        <max-object-graph-size>10000</max-object-graph-size>
        <jsr107:mbeans enable-management="false" enable-statistics="false" />
    </cache>
</config>

Hi,

It is supported in the XML configuration, you are just placing the content at the wrong place in the XML.

Have a look at the sample in the code repository:

• https://github.com/ehcache/ehcache3/blob/v3.4.0/xml/src/test/resources/configs/sizeof-engine.xml#L21 shows how to define defaults at the CacheManager level
  
• https://github.com/ehcache/ehcache3/blob/v3.4.0/xml/src/test/resources/configs/sizeof-engine.xml#L50 shows how to define these values per cache
  

I have filed an issue so that the documentation contains an XML sample - see https://github.com/ehcache/ehcache3/issues/2218.

Regards,

Louis
