Kundera allows you to specify data-store specific hooks into a configuration file. You need to add below entry into persistence.xml for your persistence unit.

<property name="kundera.client.property" value="property-file" />

Here property-file is the name of XML configuration file that must be in classpath of your application:

XML Property File

Kundera allows to specify datastore specific configuration in an XML file in below format:

<?xml version="1.0" encoding="UTF-8"?>
<clientProperties>
    <datastores>
        <dataStore>
	    <name>mongo/cassandra/hbase</name>
	        <connection>
		    <properties>
		        <property name="connection.property1" value="connection.property1.value"></property>
			<property name="connection.property2" value="connection.property2.value"></property>
			<!--  More connection properties -->
		    </properties>
		    <servers>
