Hello! For that, you can use keyConfiguration property on igniteCache:
<bean class="...CacheConfiguration"> <property name="keyConfiguration"> <list> <bean class="org.apache.ignite.cache.CacheKeyConfiguration"> <property name="typeName" value="ClassNameOfKey"/> <property name="affinityKeyFieldName" value="fieldNameInThatClass"/> </bean> </list> </property> </bean> It is poorly documented, unfortunately, I've raised submit a ticket about that:https://issues.apache.org/jira/browse/IGNITE-8253 Regards, -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
