Hello Alex,
You need to specify the number of backups for your cache. For instance,
<property name="cacheConfiguration">
<bean class="org.apache.ignite.configuration.CacheConfiguration">
... <!-- Number of backup nodes. -->
<property name="backups" value="1"/>
...
</bean>
</property>
Please take a look at the page for details:
https://apacheignite.readme.io/docs/primary-and-backup-copies
Thanks,
S.
