It would be better to upgrade to 2.5, where it is fixed.
But if you want to overcome this issue in your's version, you need to add
ignite-indexing dependency to your classpath and configure SQL indexes. For
example [1], just modify it to work with Spring in XML:
<property name="indexedTypes">
<list>
<value>org.your.KeyObject</value>
<value>org.your.ValueObject</value>
</list>
</property>
