Hello,
1) No, functions can't be overloaded. Functions with the same name must
have a different number of parameters
3) To register a class with custom SQL functions via XML just use regular
Spring bean notation
<bean id="ccfg" class="org.apache.ignite.configuration.CacheConfiguration">
...
<property name="sqlFunctionClasses">
<list>
<value>Functions1.class</value>
<value>Functions2</value>
...
</list>
</property>
</bean>
Kind regards,
Alex.
