Using Hazelcast EclipseLink Cache Coordination Protocol

Configure persistence.xml as follows:

  • Set eclipselink.cache.coordination.protocol property to fish.payara.persistence.eclipselink.cache.coordination.HazelcastPublishingTransportManager

  • Add eclipselink.cache.coordination.channel property

The channel property is optional, but is highly recommended if the application has more than one Persistence Unit. Best practice is to name the channel after the persistence unit.

Here is a complete example:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence version="2.2"
             xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd">
    <persistence-unit name="MyPU" transaction-type="JTA">
        <properties>
            <property name="eclipselink.cache.coordination.protocol" value="fish.payara.persistence.eclipselink.cache.coordination.HazelcastPublishingTransportManager"/>
            <property name="eclipselink.cache.coordination.channel" value="MyPUChannel"/>
        </properties>
        <jta-data-source>jdbc/myDataSource</jta-data-source>
        <shared-cache-mode>DISABLE_SELECTIVE</shared-cache-mode>
    </persistence-unit>
</persistence>
