Prev	Chapter 12. Configuration	Next

There are some advanced configuration properties to tune some aspects of Hazelcast. These can be set as property name and value pairs through configuration xml, configuration API or JVM system property.

Configuration xml

<hazelcast xsi:schemaLocation="http://www.hazelcast.com/schema/config
    http://www.hazelcast.com/schema/config/hazelcast-config-3.0.xsd"
    xmlns="http://www.hazelcast.com/schema/config"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    ....
    <properties>
        <property name="hazelcast.property.foo">value</property>
            ....
    </properties>
</hazelcast>

Configuration API

Config cfg = new Config() ;
cfg.setProperty("hazelcast.property.foo", "value");

System Property
1. Using JVM parameter: java -Dhazelcast.property.foo=value
2. Using System class: System.setProperty("hazelcast.property.foo", "value");
