I'm new with Ignite and I'm trying to test data quality and availability of
Ignite cluster.
I use the below xml configuration for setting cluster,
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="socketTimeout" value="50000" />
<property name="networkTimeout" value="50000" />
<property name="reconnectCount" value="5" />
<property name="ipFinder">
<bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">
<property name="addresses">
<list>
<value>x.x.x.1:47500..47509</value>
<value>x.x.x.2:47500..47509</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
</bean>
Also and jthe CacheConfiguration is,
<bean id="cache-template-bean"
class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="CACHE_TEMPLATE*"/>
<property name="cacheMode" value="PARTITIONED" />
<property name="backups" value="1" />
<property name="atomicityMode" value="TRANSACTIONAL" />
<property name="writeSynchronizationMode"
value="PRIMARY_SYNC" />
<property name="rebalanceBatchSize" value="#{4 * 1024 *
1024}" />
<property name="rebalanceMode" value="ASYNC" />
<property name="statisticsEnabled" value="true" />
<property name="rebalanceBatchesPrefetchCount" value="4" />
<property name="defaultLockTimeout" value="5000" />
<property name="readFromBackup" value="true" />
<property name="queryParallelism" value="6" />
<property name="nodeFilter">
My scenarios are,
Loaded the 5 million data when all the 3 nodes
Bring one node down
The count shows 3.75 million. (Data loss)
Bringing the node up counts 5 million again.
I tried backup 1,2,3 all resulted in the same data loss. As per Ignite
documents, appears the data loss should not happen. If this fixed, I can try
adding data when the node is down and check how it behaves.
Any suggestions, please?
