Cache ExpirationPolicy

Hi

I have a cache template marked as below in the defaul_config.xml.
I was expecting that table created as such would automatically get deleted from off-heap and backup.
This is because of the expiration policy set as below


However, I observe that these tables are not getting deleted? What am I doing wrong?




        <bean id="cache-template-bean" class="org.apache.ignite.configuration.CacheConfiguration">
            <property name="name" value="SQLTABLE_CACHE_TEMPLATE_TEMP*"/>
            <property name="cacheMode" value="PARTITIONED"/>
            <property name="backups" value="0"/>
            <property name="atomicityMode" value="TRANSACTIONAL"/>
            <property name="writeSynchronizationMode" value="PRIMARY_SYNC"/>
            <property name="statisticsEnabled" value="true"/>
            <property name="defaultLockTimeout" value="5000"/>
            <property name="readFromBackup" value="true"/>
            <property name="rebalanceBatchSize" value="#{4 * 1024 * 1024}"/>

Hi!

Are you talking about the contents of the cache or the cache itself ? 
Ignite does not delete the cache, just the entries.
