◀️ Creating Jet Workspace 🔗 HQL Query ▶️

The PadoGrid includes the HQL (Hazelcast Query Language) addon for executing ad-hoc queries. Each Hazelcast cluster you create uses the template hazelcast.xml file that has HQL already configured. If want to include HQL services in your own hazelcast.xml and hazelcast-client.xml files then you must configure them as follows:

<hazelcast ...>
...
    <serialization>
        <portable-factories>
            <portable-factory factory-id="10000">
            org.hazelcast.addon.hql.impl.PortableFactoryImpl
            </portable-factory>
        </portable-factories>
    </serialization>
...
</hazelcast>

By default, PadoGrid sets the factory ID to 10000 and the class ID begins from 10000. The class IDs increment by 1 as more of them become available. If there are ID conflicts then you can change them using their system properties as follows:

-Dorg.hazelcast.addon.hql.impl.PortableFactoryImpl.factoryId=10000
-Dorg.hazelcast.addon.hql.impl.PortableFactoryImpl.firstClassId=10000
