I checked the code Actually, you can ignore this warning ("WARNING: No user-defined default MemoryPolicy found; system default of 1GB size will be used.").
Apache Ignite applies your defaultMemoryPolicySize <property name="defaultMemoryPolicySize" value="#{200L * 1024 * 1024}"/> Or you can change your config to avoid such warning: <property name="memoryConfiguration"> <bean class="org.apache.ignite.configuration.MemoryConfiguration"> <property name="memoryPolicies"> <list> <bean class="org.apache.ignite.configuration.MemoryPolicyConfiguration"> <property name="name" value="500MB_Region"/> <property name="initialSize" value="#{100 * 1024 * 1024}"/> <property name="maxSize" value="#{500 * 1024 * 1024}"/> </bean> <bean class="org.apache.ignite.configuration.MemoryPolicyConfiguration"> <property name="name" value="default"/> <property name="initialSize" value="#{100L * 1024 * 1024}"/> <property name="maxSize" value="#{200L * 1024 * 1024}"/> </bean> </list> </property> </bean> </property> Thanks, Alexey -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
